Put-Put Boat Prototype

[papababis]

kid: IT'S WORKING!!!

:D :D :D :D

[MrKaddan]

I wonder if this kind of concept could be used for a micro water pump.. Perhaps for a desktop-sized fountain

[hamsterboy959]

[ntrmn1]

[Andyx34]

what size is the copper pipe

[Lambycapo]

i tryed to make a copper tubing 1 it just wont go i even lit a tray of cerosein and just about burnt the boat down and it still wont go. eny advice would be apreciated

[kaptainkcg]

Make sure the copper is thin enough diameter. I think 1/8" works best. (I used 1/4") Then make sure that the tubing is completely filled with water when you heat it. It only works by boiling the water inside the tube. If it fills with air, it will stop working.

[swabbster3]

make one from a pop can they go fast

[cyloant134395]

could you tell me how you bent the copper tubing, this would be much appreciated.

[kaptainkcg]

I wrapped it around a piece of PVC pipe. You have to be careful not to crimp the pipe when you do it.

[TheShaggyDA]

@kaptainkcg You can fill the tube with sand (taping the ends off) before bending to stop it from creasing.

[YaMaHaCrAzY68]

@kaptainkcg That is why you put salt in the tube and bend the ends then bend it how u want it so it doesnt crimp the pipe then just cut ur ends of and dump the salt!

where would i be able to get a copper tube if u can help out .. nyc prototype tho slow n steady wins

[kaptainkcg]

We bought this 1/4" tubing at Lowes. Home Depot also usually carries 1/4" copper tubing as well. Most designs use 1/8" tubing, which may make it more efficient. Unfortunately I haven't been able to find any yet, except on the web.

If you have a local hobby shop, they should carry it in all small sizes. I've bought some from mine before.

Automotive brake tubing works well. Get it at you local repair shop, or car parts shop.
