Ever used dry ice like this?


While watching my friend try and use dry ice for his setup, he asked me if I knew what would happen if you put it in a 2 liter soda bottle. He put quite a few pieces into an empty 2 liter soda bottle and just sat it on the floor. After about 7 to 8 minutes the damned thing exploded LOL.

why does this happen, pressure build up im guessing. Anyways, point of this was that it was cool

You got it right. The pressure build up.

Dry ice is nothing but carbon dioxide. You take a tank of liquid CO2, and release the pressure, through a screen bag. The bag will fillup with dry ice. As dry ice melts (really it sublimates) it turns into a gas, at high pressure.

If you take an empty CO2 fire extinguisher, and fill it up with dry ice 3/4 full, seal it back up, after it warms up, the tank is full of liquid CO2. (Well, will have liquid CO2 in it.)

Warning, DO NOT TRY putting dry ice in a glass bottle!!!

A Chem teacher?

He REALLY should have known better. I started making Root Beer at age 12, and I knew better then.

On a side-note, dry ice makes GREAT Root Beer!

My science teacher said not to put dry ice in a pop bottle last year......
I wonder if it was the same teacher?
probably not. It would be interesting because i can see him doing that.
That pic is a little extreme though.

LOL oh man thats the worst .

The guy didnt even clean it of or anything.
One of his friends was probably there laughin his butt off, saying wait a sec we needa pic.
LOL, hahahahaa.

When I was in school kids use to make these all the time and blow up mailboxes and such.
Now where I live its a REAL big deal because a lot of people were getting hurt.
You have to be 18 to buy it and they take your ID now.
All the dry ice freezers I see now are all pad locked because of this.
One guy I knew made one from a 2 liter bottle and it blew up before it got out of his hands and the plastic tore him up real bad.


You guys need to really be careful with this stuff.
Just because it doesnt burn like gun powder doesnt mean it isnt very dangerous.

BE SAFE.

I had a bad experience with dry ice in a pop bottle once. It blew prematurely while I was still holding on to it. Luckily I still have all my fingers, but I had welts and bruises everywhere. I didn't have full range of motion in my thumb for over a year.
