[whatalamenameaviotss]

can i use super glue? the one that you dont need to mix

[sciencetoymaker]

@whatalamenameaviotss No, super glue does not seal, bridge gaps.

Slater

[AusOiPaul]

CAn i solder it instead cause i'm lazy

[sciencetoymaker]

@AusOiPaul Solder does not stick to aluminum

[AusOiPaul]

@sciencetoymaker yeah i kinda realise when i did it and it melted the straws but thx for the advice anyways :D

[oo7101]

Can you use standard white glue?

[sciencetoymaker]

@oo7101 No, it has to be waterproof

[CrismarkRock]

can i use hot melted glue instead of epoxy glue?

[sciencetoymaker]

@CrismarkRock no, that part gets hot, it would melt

[Raymond37733]

Dear Sir,

is it better to use the silicon or epoxy.Can I use UHU glue to glue the aluminum to gether and will it withstand the heat from the candle.For birthday candle that you used can I use tea light candle .

Thanks & regards

Raymond

[sciencetoymaker]

@Raymond37733 If you have a very good engine and there is no wind, a tea candle can work, but it's slower. I used to use epoxy, then silicone for leaks, but now I just use epoxy.

Slater

[Raymond37733]

Dear Sir,

What brand do you recommend to use for the epoxy.I am using Araldite by Huntsman and it is made in Belgium.

Here in Malaysia our DIY shop does do have the wide variety of epoxy like in your country,by the way are you from USA.

Recently I was in Berlin germany I saw a put put boat and I bought it for my grandson to play.

How to avoid leaks as it takes me hours to make a motor and keep on trying to correct the leak..How to have an arch

Please advise.

Thanks & regards

Raymond

[Raymond37733]

Dear Sir,

I have written to you before on how to make put put boat.

I have tried making the motor/engine.I have followed what you have mentioned using the pattern and tape it on to the outer part of the aluminum and cut as shown .I also sand paper the inner side of the aluminum as per the instruction.

I always get a leak either at the end part or in the middle.

How long do you let the epoxy to set before going to to remove the straw.

I cannot have an arch like what in your illustration

[sciencetoymaker]

@Raymond37733 It's difficult to tell without seeing. Different epoxies have different set times. 5 minute epoxy is very strong in 15 minutes. Other epoxy takes a day to set.

If you have leaks in the engine, you can fix them with epoxy as long as the candle flame does not touch that part.

I need more information about the arch to understand what is happening.

Slater

[zapperay]

idk about you but it took me like 20 min to make this.............

[frankydelavilla]

@frankydelavilla

[xy7ucq]

can u use something instead of aluminum

[xy7ucq]

can you use something instead of aluminum

[vrbdhghds]

can i use hot glue instead of epoxy

[mirzairl]

Can u use other kind of glue? if dont have epoxy

[ohmygodlookatherbutt]

If you dont have any apoxy and like to fix cars you may have fiber glass resen and hardner, this works well it just takes longer to dry

[sciencetoymaker]

@sweta244 hardware store

[157ghsrty]

im going to use leak-fix made by plastic padding its for sealing cracks on car engines so its heat resident as well as waterproof and sticks well to metal. ill post back later if it works

[157ghsrty]

@157ghsrty it works, i had a small leak between the straws but this was sealed with the glue gun when fixing the straws at the right angle. this leak-fix is more of a paste and go's hard very quickly so dont put to much hardener in the mix. its not runny like apoxy so its hard to get it in between the folds so i did'nt bother, i coated the hole side and it sealed first time.

[sciencetoymaker]

@157ghsrty It's worth a try. Some products like JB Weld are brand names of epoxy formulas.

Slater

[KILLSWITCH220099]

@sciencetoymaker i tried jb weld but it didnt work the first time but i added more and waited over night and it worked that tiiime. thanks for the epic vids now i can show my cousins and show them how to make one. :)

[oldfacefull]

I know you urge people to use epoxy as shown in the vid, but i live in b.f.e. a long way to walmart. will super glue work?

[sciencetoymaker]

@oldfacefull Super glue seems to work for gluing things together but not sealing, which is just as important. Super glue and silicone sealant might work.

Slater

[oldfacefull]

@sciencetoymaker nah it didn't work. but i found an even better thing...I just cut two pieces of aluminum identical to each other and j-b welded them togather one flat and the other somewhat bowed. still setting up though, i'll tell you how it works.

[sweta244]

@sciencetoymaker where did i get the glue

[sweta244]

@sciencetoymaker where did i get the glue

[airliners321]

can i use hot glue instead?

[sciencetoymaker]

@airliners321 Not on this part, it gets too hot. The hot glue would just melt. I urge people to follow directions the first time exactly. Try variations after.

Slater

[zdanz25]

can u use solder to seal all the folds?

[sciencetoymaker]

@zdanz25 Solder is used on the Indian engines, but they are using brass and steel, not aluminum. You have to use a special kind of solder for aluminum. I don't see it sold at hardware stores. I've heard it contains cadmium, which is very toxic. Then you would still have to the coating on the aluminum cans.

Slater

[firedude201234]

be sure to doe the epoxying outside or ina well ventilated area...too much of the fumes can be extremely dangerous and even deadly

[sciencetoymaker]

@firedude201234 Well, if you were using it in a cardboard box it wouldn't be good. It smells bad--and I wouldn't use it on food-contact surfaces--but epoxy is less toxic than solvent glues, fingernail polish, paints, hair spray, etc.

Slater

[anorup]

@sciencetoymaker While not being an expert on epoxy, I have always been taught that skin contact is very unhealthy. I wish you would recommend the use of gloves, especially as the video is directed at young people.

[sciencetoymaker]

@anorup Well, the package says it is a skin irritant. I have not read that any of it passes through the skin into the bloodstream the way some volatile solvents do. Thin gloves are disposable. That would be 3 pairs per student, times 200: 600 pairs of gloves. We do wash it off our hands. When I revise the instructions I can urge more caution when using epoxy.

Slater

[born4volleyball888]

well, is there a substitute for epoxy? like maybe shoe goo? 

[sciencetoymaker]

@born4volleyball888 Let us know if it works.

Slater

[Libed24]

@sciencetoymaker

hi

mr slater, can i use pvc cement insted of epoxy?

pls reply

thanks advance.

Mark

[sciencetoymaker]

@Libed24 I know epoxy works. I don't know about PVC cement. That is a solvent glue with fumes worse than epoxy. Why would you want to?

Slater

[Libed24]

@sciencetoymaker

because i think it might hold the pressure in the engine.

so what do you think? please reply.

advance thanks

Mark

[sciencetoymaker]

@Libed24 At the beginning of the instructions I asked people to follow the directions exactly the first time. That means use epoxy the first time, then experiment. Write down the word "epoxy" and take it to the hardware store with you. You should be able to get it even in the Philippines.

My guess is that PVC cement is solvent with a bit of pvc dissolved in to thicken it. When dry you only have pvc, which melts. Not a good glue for a hot engine.

Slater

[Libed24]

@sciencetoymaker

thank you very much mr Slater....

now i have a completely functional and working boat....

thank you.. ^_^

Mark 

[Libed24]

@sciencetoymaker

oh

can i solder the flaps for more strength?

please reply

thanks advance

Mark

[sciencetoymaker]

@Libed24 You need a special solder for aluminum, and you would have to sand off the coating on the cans. Use epoxy the first time.

Slater

[texaslonghornsruleya]

Can you use a hot glue gun instead of apoxi glie?

[sciencetoymaker]

@texaslonghornsruleya No. The engine gets hot, the hot glue melts.

Slater

[Libed24]

@sciencetoymaker

hi

mr slater, can i use pvc cement insted of epoxy?

pls reply

thanks advance.

Mark

[weyetchoc2]

what about contact cement instead of epoxy? does that work?

[sciencetoymaker]

@weyetchoc2 I don't know. It might be worth a try.

Slater

[peanutmaster1231]

okay. so i've built the entire engine and boat, and i got it to go around and around my bath tub. but- the candle has to be super close to the aluminum engine, and it takes maybe three or four minutes to start up the engine after the candle is lit. any suggestions?

[sciencetoymaker]

@peanutmaster1231 Try shaking out the engine completely and prime it again. It should start working in 30 seconds, not 3 or 4 minutes.

Slater

[peanutmaster1231]

by the way, why did you put the high pitched fast motion voice in the end of every video?

[sciencetoymaker]

@peanutmaster1231 Oh, that! I forgot it was there. I was trying to get people to stop and complete the step before they forgot the details, in way that would make them laugh. I stopped doing it I think in all the videos after that. Now I use a page turn transition and sound, as in the recent origami hang glider project. I'll remove my other comment. I thought you were insulting my regular voice. Guess I'm a little oversensitive...and forgetful.

Slater

[peanutmaster1231]

@sciencetoymaker haha okay. another thing, I JUST GOT EPOXI ON MY PHONE BUTTONS AND ITS STARTING TO SET HOW DO I GET IT OFF!!!???

[sciencetoymaker]

@peanutmaster1231 Vinegar works like magic to clean off sticky epoxy.

Slater

[peanutmaster1231]

where can i buy epoxy glue?

[sciencetoymaker]

@peanutmaster1231 Any hardware store, and be sure to get the 5 minute / quick setting kind.

Slater

[peanutmaster1231]

can i use super glue? if not, what are the two parts made out of?

[sciencetoymaker]

@peanutmaster1231 If you get super glue into the folds of metal, it holds the shape. The problem is that thin super glue leaks, and the engine won't work with even a pinhole leak. Somebody said they had a kind of gel super glue that did work.

I encourage people to follow instructions exactly for the first engine. I don't like epoxy glue either, but it's available in any hardware store, waterproof, fairly heatproof, and fills leaks.

Slater

[peanutmaster1231]

@sciencetoymaker okay. thanks! i did find it at my local hardware store. i absolutely hate the stuff, but if it will make it work, then im happy. my friends bet me that i couldnt make a working self propelled boat out of trash. haha im gonna show them...

[sciencetoymaker]

@peanutmaster1231 I know this is frustrating for people to hear, but virtually everybody has to make a second engine before they get it to work. And all I can say is, yes it's a lot of work but it's worth it. Like you said, how many of your friends have built their own engine? Keep plugging away. Let me know how it goes.

Slater

[peanutmaster1231]

@sciencetoymaker i know, i already tried to build one. ^.^ i didnt pay enough attention to the video so i used super glue... it didnt work and i was wondering if that was the problem.

[raggnar111]

could i use plastic cement

[sciencetoymaker]

@raggnar111 I don't know.

Slater

[BladeZp3]

can i just use some other glue like uhhhhh normal glue

[sciencetoymaker]

@BladeZp3 no

[TheSuperpotterman]

can i use a glue gun for this part

[sciencetoymaker]

@TheSuperpotterman No, this part of the engine gets too hot. It would melt hot glue

Slater

[coolcamryCP]

@sciencetoymaker how about cheap glue?

[sciencetoymaker]

@coolcamryCP no

[sciencetoymaker]

@TheSuperpotterman no

[ohmygodlookatherbutt]

can i use a fiber glass resen with some hardener instead of apoxy?

[sciencetoymaker]

@ohmygodlookatherbutt I don't know if that would work or not. If you try, let us know how it works out.

Slater

[ilovesteaksnscience]

do you think i can use 6mm straws for the shape but glue in 5mm straws cos' i only have 5mm bendy straws? good luck on solving the mysteries of pop pop boats!

[sciencetoymaker]

@ilovesteaksnscience I have made engines with the thinner 5mm straws. I did get some to work, but they were trickier to deal with and not a loud. Let me know how it goes.

Slater

[ilovesteaksnscience]

hey sciencetoymaker. i've made a couple of pop pop engines already but the cheap 5 minute variety of epoxy seems to make my engine more effecient than the 15 minute variety...What do you think about this?

[sciencetoymaker]

@ilovesteaksnscience Hmmm, that's an interesting question. I only use the 5 minute epoxy, so I don't know. There is certainly lots of mystery left in making these engines. Occasionally one will appear to be perfect, but not work. I have made a couple of dozen engines in the last 2 weeks to find the variables that occasionally perplex me, but I'm more perplexed now than when I started!

Slater

[jasonmathew33]

does any1 know where to get epoxy in south africa, gauteng, johhannessburg

[sciencetoymaker]

@jasonmathew33 I have a good friend who lives in Durban, so I e-mailed him. His response: "You can get it everywhere, in hardware stores and even in supermarkets. There are a number of brands, all called epoxy."

[jasonmathew33]

@sciencetoymaker thanx alot i found epoxy at my local hardware store! 

[RcMasta90]

do u have to use epoxy? can I use hot glue or super glue?

[sciencetoymaker]

@RcMasta90 It's best to follow directions exactly the first time. Hot glue will melt when the engine gets hot. Super glue can have trouble filling gaps to make it air tight. One person reported some success with super glue and silicone.

Slater

[kiepskipolak]

umm

will black concrete/steel epoxy work?

its is brownish blackish

[sciencetoymaker]

@kiepskipolak Yes, any epoxy will work, although some might take longer to set.

Slater

[KesleyWORKS137]

We're making putt putt boats for a physics project and you have no idea how much this has helped me!!! You explain every detail so well. Thank you so much!

[sciencetoymaker]

Thanks for the encouragement

Slater

[95myers]

it din't work hehe

[95myers]

i'm using silicone i think it'll work okey

will it? i just can't get epoxy

[sciencetoymaker]

Epoxy might be available, but called something else. I did hear from a gentleman who used super glue to hold the shape, then silicone to seal. And he said it worked. So you'll have to experiment.

Slater

[ecaslimjim]

would JB weld work

[sciencetoymaker]

Yes, JB weld is a brand name of a particular kind of epoxy.

Slater

[qwert0t]

would using 1 bendy straw cut in half to 2 pieces work?

[sciencetoymaker]

@qwert0t Not sure I understand the question, but no. Follow directions exactly the first time through. Try things once you have one working.

Slater

[alexelperron]

where can i get epoxy?

[sciencetoymaker]

@alexelperron Any hardware store

[cashg67]

can i use a glue gun

[keivo2]

if i stick in the straws i hear motor sound :D

[keivo2]

done!

[gheorghe20]

man,your so cool,my first engine and it works,i used super glue instead of epoxy and hot glue gun.thank you,im a fan of this thing now

[rocketman468]

why do i have to use epoxy glue? why cant i use another type of glue?

[sciencetoymaker]

Other glues might work, but I know that epoxy will work.

[choco33333333]

ill just use regular elmers glue

lol

[sometimestommy]

will shoe goo work?

[sciencetoymaker]

I don't know.

[711song]

i used a super hard substance that you need together and dries in 3 min...but i couldn't get it in to the cracks very well...

[joe244jenne]

Can you use super glue? Need help!

[sciencetoymaker]

Follow the directions the first time: use epoxy. Then experiment with super glue and let us know how it works.

[jeroen141993]

wtf it aint working for my men :S my boiler pattern is ways smaller than yours.. and with the gluwing part there aint coming out the inside of the boiler

[sciencetoymaker]

If your boiler pattern was scaled down, that could be the problem. Check the print windo before printing for "no scaling" or something to that effect. And measure the scale checker to make sure. Let me know.

Slater

[sciencetoymaker]

I don't know. Try it and let us know.

Slater

[yeshodeep]

while sticking the aluminum can i use super glue instead of epoxy glue

[sciencetoymaker]

I don't know. I would follow instructions the first time unless you absolutely can't get epoxy.

Slater

[csm19770401]

it´s fantastic, great, amazing...thank you very much for sharing this

[REECE780]

also i used cement glue but u no how u got a bit of metela and ran through the side i did that as well mude i moved the metal around a bit

....

[RIDETHESNAIL]

can u use cement for plastic models clue cause im using tht

[sciencetoymaker]

So RIDETHESNAIL, did it work?

Slater

[DarthWilius]

Can I use silicone to glue it ?

P.S this is an awesome instruccion video

[sciencetoymaker]

re: silicone instead of epoxy: I don't know if silicone will work or not. It will certainly take longer to solidify. Epoxy is sold in any hardware store and not expensive. I suggest following instructions exactly for the first engine. Experiment after you make one that works.

Slater

[sciencetoymaker]

Well, if you are using steel and brass as a typical engine does, you can. But this uses aluminum, which cannot be soldered with ordinary solder. Aluminum solder contains cadmium, which is very toxic.

Slater

[pcsuper1]

darn i just solderd it and it took a long long time (cause i havnt worked a lot with that solder tool), i tried it and what would you think, it didn't work

i think I'm going to buy some of that stuff:D

PS: before i tried it using a glue gun but that kinda didn't work either, is it just me, or can't it be done anyway....

[AlexFaulkner2294]

can i use black epoxy? the stuff that has a white part and a black part that you mix together. thats all i could find at my house.

[sciencetoymaker]

Yes, epoxy comes in all different colors, thickness and set times. As long as it's epoxy and has two parts that mix together, it should work.

[80VideosMan08]

yeah, ur right,...

i told my dad and he brought it for me from a normal shop lol

its sticks man

lol

really stinks

[F4k3rg0pr0]

where can i buy epoxy? in west bank? what store?

[sciencetoymaker]

Most any hardware store should sell epoxy.
