dry ice experiments by ins4ne on 10-21-2006 at 08:20 AM

i just found a video of some guys, playing with dry ice. (hey, that rhymes :D) anyways. here the vid. so my question; where can i get dry ice from?

edit: there must be a way to get it cuz they have ;)

unfortunately, if you live in the Uk, like me. You are unable to purchase "dry ice" for.. obvious reasons, unless of corse u have authority, that you are going to use it for work/learning related reasons..

edit: although if you dont live in the UK, im sure it wont be hard to obtain some.. this could help how to make a dry ice bomb- you tube

I'm sure ice cream trucks use dry ice *-) But I'm not sure they're just going to let you have some (it's not exactly a secret what you can do with it)... unless you ask nicely and say you need it for a picnic or something, although that wont work atm as it's coming into winter. Other than that it's pretty hard to get hold of some unless you are a school or company ordering it for a valid reason other than using it for bombs.

That has to be the most poorly made video on youtube. It says 'how to make a dry ice bomb', yet does it do this? No, it shows a guy putting dry ice in a bottle and that is it. He needs some lessons in making home videos.

We get some with some meals mum gets from her work (she works for a diet food company) and it is heaps of fun, though I've never made it into a bomb (would require the lid to be really tight).  I once made a stand/launching pad out of some old lego and used a water bottle to launch it straight up into the air.  It went so high that it literally took like 20 seconds for the bottle to appear again.  It was very fun, my next plan (when I can be bothered) is to get some poly pipe and make like a rocket launcher out of it (6)

Using dry ice (solid carbon dioxide // carbon dioxide = CO2) can cause serious burn wounds!!! Be extremely carefully if you need to handle it. Never touch it directly (although you can get away with it if you know what you're doing).

Dry ice has a surface temperature of around -80°C. The extreme cold will give you burn wounds. If you keep it under pressure and it explodes (dry ice bombs) it can not only cause severe wounds, blindness (small parts shooting in your eyes; doesn't even need to be at high velocity; the freezing cold is enough), and even damage to your ears because of the intensive explosion.

NEVER EVER lick, taste or even swallow it, even a tiny amount will get you in hospital and give you permanent wounds. This includes putting dry ice in drinks! Or accidently getting dry ice in your eyes...

---

You can get dry ice in many forms.

The liquid kind is as good as impossible to get (liquid CO2). Also don't confuse the liquid form with liquid nitrogen (which boils at avg. -200 degrees!) and often seen to flash-freeze stuff.

Dry ice is a solid and sold as big chuncks/blocks, crunched in smaller chunks or as small kind of marbles.

You can buy it easly from specialized companies, welding shops, sometimes ice cream places, chemical supply houses, etc.

Also don't confuse the smoke you often see in theater and stuff with the smoke from dry ice. Although dry ice is often used for it, it also is a specific kind of very low hanging, crawline, dense and intense white smoke. In many plays you also see "not so dense" smoke, the cheaper variant. This is caused by lowering the temperature of the smoke which comes from ordinary smoke machines (used on parties for example).

I handled kilo's of dry ice on a daily basis for almost a year (used for FX in a big musical play). And still handle it now and again (again for theater related stuff).

I strongly suggest NOT to play with dry ice, especially not experimenting with dry ice bombs. It is as dangerous as playing/experimenting with fireworks!!!

To proof that this is not as safe as you might think search the net for the accidents which can happen extremely quickly.

My then three year old son was seriously injured, He lost one of his eyes, his right thumb was 75% severed and broken, his left thumb was 50% severed and he had a gash about 4 inches long on his stomach. I had also never heard of this and was mortified. My son is now doing wonderful and we are very vocal about it to let people know what can happen with what I found out after the fact to be called "dry ice bombs".

I've used it, I'm in the UK. o.O But I have absolutly no idea how/why it was purchased.

* Chris4 stays well clear of any dry ice :|

If you're in the US. you can buy a block of dry ice at Walmart.  I've played with dry ice bombs before, and as Cookie said, they can be VERY dangerous.  A friend of mine got hit with a bottle cap when we were playing with them, and it left a nasty and very painful welt on his chest.  He ended up having a bruise the size of half a dollar bill.

Though, it was fun.  Try tossing a whole block or two into a swimming pool.

Same as what would happen if you poor water over it I guess.

The block will sink to the bottom and will quickly start to boil, giving out gas bubbles which will rise to the surface and which will leave a tick white low hanging smoke.

(unless the pool is less than 10°C, which in that case you wont see smoke at all.)


@ins4ne: I left you a PM
