Water Thermometer - Sick Science!

[ryccalamucha]

My conclusion is that because when molecules are hotter it goes through other molecules making it move faster and making it rise because they need more space to go to hence the hot water while the cold water is simply the opposite the molecules move slower and need less space so they go down. YAY i just learned that last week :D

[Jaesango]

water's density lowers as it gets above and below 4C (1 g/cm3) which causes it to expand

[Funnyman850]

convection

[NoahTheAmazing9]

Could this be convection maybe?

[social3ngin33rin]

air under the molding clay increases in temperature making it's volume increase forcing water in the bottle to move up through the straw while in the hot water. and vice versa if it were placed in the cold water

[DreamCatcher365]

and the mystery continues about what face belongs to those arms O.o

[Haemoclysm]

The glass shattered and broke my house.

[colin571]

@Haemoclysm A glass bottle broke your house...? Is your house made of paper?

[DaleJohnPorter]

@colin571 I would love to see a paper house stand up.

[gandraswow]

@colin571 dont make fun of him, we arnt all able to have a cardboard box like you

[ArsonistInUrFirewall]

@Haemoclysm

Really, is your bottle the size of a bus, or is your house made of cards?

[Flameon7112000ll]

@Haemoclysm do you mean it fell onto the floor and cracked the flool??

[riotact78]

@Haemoclysm You lives in a cardboard house.

[HELLHamster16]

but whats the temperture?

[19CroatiaPower98]

Clever design! Should be able to run on diesel as well? The opposing pistons remind me of the Napier Deltic engines, but they're not rotary engines....

[chsxtian]

@19CroatiaPower98 Interesting concept, a thermometer running on diesel.

[Phenomiphy]

Hot water is expanding making the water rise xD

[JCfan0019191]

The expansion and the contraction of water? I learn this during primary/elementary school

[mrazlan9876]

why dont u use metal for better conductor of heat......

[Dark0Lord7]

@mrazlan9876 Mercury is too dangerous.

[skar02]

@Dark0Lord7 I think he meant a metal container.

[Rafterman123]

It's not really a thermometer if it is not calibrated... God! Do I have to think of everything!

[whynabile]

@Rafterman123 thermo=heat, meter=something that measures

so anything that measures heat is a thermometer, doesn't matter if it's on a system or not

[h077ings3ad]

why not present a real conundrum to your audience like, how does ice skating actually work?

[mjpalmer3000]

i got something like this from a museum once, it had 2 glass sections connected by a thin glass pipe, and when you placed your hand on the bottom, the heat from your hand made the liquid go from the bottom to the top through the glass pipe :P

[iClutchGranade]

it make a mess and i got grouned for a month becouse i droped the bottles and it got everywere

[JonaVicis]

Think about this: If water expands as it freezes, why does it contract here as it cools?

[idiotAREstupid]

@JonaVicis Water contract when it cool down and expand when it cool down to freezing point.

[LacasseMathieu]

@JonaVicis because water, like most things, contracts when it is cooled. It is the Hydrogen bonds that are formed as water freezes that cause it to expand.

[minxel16]

@JonaVicis because it only expands at the point of freezing, but providing it is still a liquid, it will expand as it becomes warmer nearing the phase change to a gas and contract when cooled as long as it doesnt reach freezing point.

[UniversalHere]

i could have answered this in 3rd grade -_-

[TheSuperMenzo]

Step 1. Get the hot and cold water

Step 2. TOUCH them

simple as that

[kromata1]

??????????????????????????????­????????

[antiquatedannomaly]

do some people seriously not know how this works??

[UKRAINERULES253]

that message in the end of the video the red letters spell science

[phineasandferbize]

@UKRAINERULES253 it s in evrey one

[voiceofreason2008]

it is to with expansion and contaction mollecules

a similar set up can be used as a barometer for atmosheric pressure

it involves a bottle filled with water about half full turned upside down in water (coloured for ease of viewing) held so that the lip of the bottle is just below the surface, then you can monitor differences in the level of water to read atmospheric pressure

high water level in bottle means high pressure

low water level in bottle means low pressure

[Maclanemast]

Hot things expand and cold ones contract...

Earth science :)

[mentalleevoid]

This is clearly witchcraft. The colored water is being forced through the straw by the Devil himself. Have you tried using Holy water?

[12309tyler]

Basically when heat

[WalirutoelZ]

the water molecules in the bottle which is in the hot water need to move around more and then take up more space and in the cold water the molecules move around a lot less take up less space.

[WalirutoelZ]

the water molecules in the bottle which is in the hot water need to move around more and then take up more space and in the cold water the molecules move around a lot less take up more space and so in the hot water the colored water in the bottle move up the straw and in the cold water u wont notice anything but the water is taking up less space.

[poopsicles50]

Heat expands, cold shrink :)

[rthoma34]

We did this in middle school at my school. IT WAS SO FUN!!!

[MrVatanchaudhary]

this is because when the temperature is increased the intermolecular forces between water molecules increases thus water expands and it comes out through straw

[kennyb0y1597]

i did this without knowing it when i was like 5

and i left my soda in the car and the so the soda went up the straw and we were all like wtf and the soda wasnt sealed

[rcj2995]

Mine is not working ?? x| I need help for our Science Fair.

[lisapurple89]

did that in school

[kingivanthe3rd]

the video before this was funny lol the baloon was happy

[EbilinforcerDJ]

It is a principle of Capillary Action, Where colored dye is expanded by water and the

molding clay and the straw is where the excess is expanded from the heat. this is a

simple experiment where i did this in 4th grade (4 years from now.)

[xNrGSwitchblade]

this happens because when heated, water expands, i assume everyone already knows this...

[LetsGoRiotThisBitch]

Stevespanglersscience, Is there an acurate way to put number markings on the straw so I know what the tempurature is?

[zazaalobffs4ever]

who is tht dude?? is that steve spangler?? kinda looks like he lost some weight! lol no offense!!!!!!!!! :)))) but probly a diff guy

[zazaalobffs4ever]

cool

[zazaalobffs4ever]

who is tht dude?? is that steve spangler?? kinda looks like he lost some weight! lol no offense!!!!!!!!!111 :)))) but probly a diff guy

[flamer246360]

is everything u make sick sccience

[kuttu45454]

actually the bottle should break , cant bring an cold body in contant with hot body , wat if there is no straw

[rbandgh3]

blue magic

[themaster703]

whoa!

[ackerman66]

the basics of a galileo thermometer

[panzuman]

@ackerman66 extreame basics

[JTS24]

The water molecules become more "excited" when they become heated by the hot water tank and bounce around more vigeriously. Bounce around enough and they break their bonds, becoming a gas. Cool down the liquid and the bonds strengthen, causing them to come closer together. Not sure how to explain how ice seems to take up more space than liquid though... seems counter intuitive to me.

[facebook19901]

OK NOW HOW DID IT HAPPEN!!!.......P.S. i need a science project

[islandfireballkill]

the water and air in the jar expand because of heat and since the jar is sealed it pushes some water up to make space for the gas

[pkmnmaster760]

Easy hot water expands and cold water contrasts. 

[RegicidalFreak]

@pkmnmaster760 Contracts*

[itzJustxP]

When something is exposed to something hot, the particles start moving more, making the water go up the straw.

[SuperMagickid1000]

my conclusion is because when the bottle is in the hot water container,the bottle gets heated and the ''blue water" starts to rise up, if it is set on a cold water container the water starts to drop down just like in his other expirement when he puts a lighted candle inside a test tube on a container full of water the water rises up so they are using the same details but now at this video they use other stuff to do it. thumbs if i am right.

[Balgangsak]

nice

[linusheim]

the water molecuels expand when warm and the straw will only let water rise

[bluegirl99ful]

Hot air rises

[OrigamiFreak1000]

Woah :D

[Striker5551]

I think the difference between the hot and cold creates a pressure difference that forces the water up the straw

[07PamPer07]

The water expands because of the temperature difference

[vasko002]

Water expands when heated

[stupidahg]

Uses expansion of matter

[epicawesomesauceguy]

I think, the water increases air pressure, and pushes it through the straw based on how hot or cold it is

[jocax188723]

Water expands as it is heated and contracts as it is cooled.

[bennystheman]

Hot things expand, cool things contract.

[darkstar744]

Ooo! secret video! xD

[PHPManTut]

Old Music Back :D :D :D

[FORCE153153]

@PHPManTut YAY!!!! :D :D :D

[thepinkmagic205]

Oh.....cool :D

[jedisponge16]

@andreasfr1 It's standard procedure

[TheJustinSean]

Just remember if at first you don't succeeded....your nor Chuck Norris!!!

[spiker369]

@TheJustinSean *you're not

[rav3ntm]

The man is like a robot :D

[Ssamme11]

nice :)
