Brainiac - Thermite And Ice

Aug 26, 2010 - Ahh this is the only thermite one I remember and I talk about it all the time

Nov 9, 2010 - I GOT TO PAY WITH THERMITE IN SCIENCE TODAY! WOOHOO, IT WAS AWSOME!

Nov 11, 2010 - I am agreeing that a sublimation of the water expanding ridiculously fast making something like a thermite cloud is more plausible, or even like a plugged gun barrel as the pressure from the steam is enclosed ...reaches a breaking point and explodes while flinging molten metal everywhere.

Jan 19, 2011 - The definition of a "high explosive" is a solid that violently and quickly turns into a gas. that is what is happening to the ice. the heat of the thermite is strong enough to change the state of matter of the ice on the INSIDE of the block faster than the outside, suddenly creating a BOMB

Jan 25, 2011 - i once read that water when its heated really hard it turns into solid

Jan 28, 2011 - rchard should remain on top gear

Raeuber13 Says:

Jan 28, 2011 - it is only the pressure of the steam

tnnguye3 Says:

Feb 13, 2011 - Well, If you heat matters until it's hot enough, I think it'd turn into plasma, right?

2020man996 Says:

Mar 9, 2011 - Rickysaltacorp are you an idiot or didn't take basic science? It would sublime to a gas. It's a solid when it is FROZEN. However other elements may behave like that.

Mar 15, 2011 - hey there it may not at 200 to 500 degrees Celsius, but at 2000 degrees Celsius It might(bond enthalpy) correct me if I m wrong

Apr 1, 2011 - This shows how this "maniacs" are full of shit.

frother Says:

Apr 4, 2011 - what. at a million degrees water would separate into hydrogen and oxygen.

HardstyleStormz Says:

May 2, 2011 - No, and im not even gonna bother explaining to you why that is retarded.

HardstyleStormz Says:

May 2, 2011 - Lets say that ice weighs like 20kg (I'm just judging by the size, could be a lot more or a lot less).10kg of pressurized hydrogen and oxygen would have exploded beyond belief.Thus, it has to be water turning into steam rapidly.

peonatre Says:

Jun 1, 2011 - heat and electricity are both energy and can have the same effect

TimelessFarmer Says:

Jun 7, 2011 - The reality is that nobody's entirely sure -why- thermite and ice is an explosive mixture and there are many conflicting theories. You can decompose water into hydrogen and oxygen (which explodes with ignition) with heat, as you can decompose anything if you give it enough energy to do so. I doubt it is the one, personally, as I think there's not enough energy to do enough of said decomposition for the explosion. But it's still a valid theory.

electiveelf Says:

Jul 28, 2011 - actually as hammond explains the heat would break the molecular bonds breaking down into its component atoms hydrogen and oxygen. hydrogen is flammable and will explode causing another reaction making water vapour.

italiansoccerrulez Says:

Aug 2, 2011 - no..... it will just explode, no second reaction. A Combustion reaction doesnt create H2O it creates CO2

2010saboor Says:

Aug 3, 2011 - shut up

ellfangor8 Says:

Aug 7, 2011 - incorrect, 2 hydrogen + oxygen + fire = water

CertifiedBad4ss Says:

Oct 2, 2011 - did you record the sound with a calculator?

LucaTurilli89 Says:

Oct 4, 2011 - the video is from 2008 and I guess the codecs suck :D.

CertifiedBad4ss Says:

Oct 30, 2011 - If you stick an ice cube under tap water (which is like 10degrees Celsius) it will fracture, imagine what happens to ice when its exposed to 2000 degrees hot thermite, it will explode.
