Introduction: How to Make Flammable Ice (yes-solid Water)

Ice is quickly added to a dry Pyrex bowl. Not Dry there is Calcium Carbide on the bottom, that is why you do it quickly. When the Ice melts the water reacts with the calcium carbide (place on the bottom) to produce acetylene gas and calcium hydroxide. The acetylene gas then explodes into flames when a match is place on top. It will continue to burn even as the ice melts because it keeps producing acetylene until the calcium carbide runs out.

and where do u go to get calcium carbide anyways?

Zack3245 (author)2012-08-29

Does the match have to be lit or what. I'm not sure.

Matt D655 (author)2008-07-19

gasoline or kerosene

pickford78 (author)Matt D6552008-08-22

calcium carbide....not dinosaur fuels

I think I have about 1/2 a horseshoe crab going for mine.

It must be nice to be a teacher and have chemicals at your disposal.......

calcium carbide is sold as weed remover

also, as a product called "Bang-Site". the company produces old replica cannons that use the bang-site to fire. they shoot no projectiles. they are located somewhere in eastern PA (bethlehem maybe?). my dad and i didnt want to spend 300 dollars on one of their brass civil war replica cannons, but a few bucks for a tube of calcium carbide didnt seem like a bad deal. then we made a PVC cannon and before long we were launching 34mm superballs 100 yds easy. the stuff is powerful. i should post an 'ible on how to make a bang-site cannon :-)

i would like to see that   i want to use it for paintball mortar....have to see if ball disintegrate at launch

beanie larue (author)j626no2008-12-31

check out backyard ballistics by William Gurstel which has a plan to make a carbide cannon but it sells for 18 dollars in America or about 9 British pounds if I'm correct

Fizzxwizz (author)beanie larue2009-07-02

I have that! Its a great book!

j626no (author)j626no2008-08-29

before batteries were convenient, miners would use calcium carbide for their headlamps. at the start of their shift they would place a small amount of CaC2 into their lamps with water. I think the water would slowly drip and the acetylene gas would then keep the small flame burning. this reflected off a mirror to make a respectable lamp...cant remember if any exploded or not though :p

To the Garden center!

you should get some potassium nitrate while your there (sold as a stump remover) it can be used to make gunpowder and smoke bombs

Notbob (author)twenglish12009-01-31

i should just like to point out, a lot of places wont sell Potassium Nitrate to minors, purely because it can be made into black powder.

iBurn (author)Notbob2009-01-31

Pfft. E-B-A-Y If I can buy Uranium off of Amazon...I can buy KNO3 from Ebay.

Jaycub (author)iBurn2009-03-05

Wait, how do you get Uranium?!?

twenglish1 (author)Jaycub2009-03-05

you have a few options, you can buy it, mine it, or steal it, i would recommend buying it, i think united nuclear has it

Fizzxwizz (author)iBurn2009-07-02

The reviews on that page are CLASSIC!

iBurn (author)Fizzxwizz2009-07-05

Awww man, it's incredible.

Jaycub (author)Notbob2009-03-05

I'm 16, they don't ask any questions when I buy it.

iBurn (author)Jaycub2009-03-05

I thought you had to be 18... o.O

twenglish1 (author)iBurn2009-03-05

no you don't

twenglish1 (author)Notbob2009-01-31

yah i know but most likely people won't know that certain stump removers are potassium nitrate, and they probably won't care either

iBurn (author)pickford782008-08-22

Haha, No kidding (author)iBurn2008-05-07

I agree. I want to blow stuff up too! :P

no vid KNEX freak (author)2008-04-10

please make a vid showing us how to make it

you put chunks of calcium carbide on the bottom , then place ice on top and the melting ice reacts with the calcium carbide to produce acetylene

Don't you use acetylene when you weld???

YoungPyro19 (author)2010-06-04

Sweet! That is so cool. I have to try that.

Plasmana (author)2008-10-01

That is cool!

quillbom123 (author)2008-09-19

we tRied to burn ice and it DIDNT HAPPEN!!!!!!!!!!! ARGH!

Comeaja (author)2008-03-11

Note when he has the ice sitting alone, before throwing the first match, you can see little trails of mist trailing off the left side of the container.

that is the ice vaporising

pickford78 (author)2008-08-22

put it in water and it produces hydrogen :P but yes conrad2468 answered your question>2.Ca(OH)2+ 4.H

pickford78 (author)2008-08-22

its water with calcium carbide in it

conrad2468 (author)2008-07-30

calcium carbide....not calcium....

Doctor When (author)2008-03-04

that is so awesome
