[LINK] This video (high speed link recommended) shows show kids trying to get a "dud" dry ice bottle bomb to explode.
The result is not really funny, and should be a lesson to kids everywhere, but I couldn't help chuckling during the clip. See if you can.
This is why the GT custodian can be considered LUCKY to only have some ringing in his ears after the Freshman left a dud on campus.
If you just can't resist trying it, instructions are in the continuation.
DIRECTIONS (but don't do it!)
You will need:
Dry ice -- can buy at Publix
Water (adjust temperature according to ambient conditions to control speed)
PLASTIC coke bottle
What you do is take some dry ice and put it in a coke bottle. Fill
the bottle with hot water. Once you are in an open area put the lid on
the bottle. It USUALLY won't explode in your hand. Throw the bottle ASAP. It
will USUALLY explode. If you use a very thin glass bottle, somebody (perhaps yourself) might die.
If it's a dud, it's YOUR RESPONSIBILITY to deactivate it so no innocent passersby are hurt. That part is "left to the student."

Carbon Dioxide Pressure Device:
===============================
Materials: Bottle or jar, dry ice, water [optional].
As with the hydrogen device, we have had greater success with seltzer bottles than with jars. Once again, it is assumed that you have a good cap or lid to prevent the carbon dioxide gas from escaping. Dry Ice can usually be bought from an ice cream store for under $1.50 a pound. Dry ice does not keep long [it becomes gaseous at -109 F] and refridgeration will help little. Water can be used to speed up the device's reaction.Procedure: Break the dry ice into chunks that will fit in your bottle. The more dry ice you have, the faster the reaction. Cap the bottle tightly, and quickly clear the area. If you need a fast reaction, add water to the bottle before capping. The reaction's speed increases with warmer water.. Be careful
not to get a reaction that is too fast. People have had these devices blow up in their faces because they used hot water and didn't clear the area fast
enough. Take into consideration the temperature of your site and excercise caution on hot days. We strongly advise against using hot water in this bomb! [Unless, of course, you have a death wish]
Observations: This is a very economical and simple bomb.It can be extremely dangerous if the user is careless. By using water of different temperatures, one can roughly control the speed of this bomb's reaction. We've had a few close calls with this bomb, so we don't use water in it anymore. The reaction goes fast enough without water..
This reminds one of the mythical Polish hand grenade, with an explosive radius of 25 feet and capable of being thrown 15 feet. You're about as likely to hurt yourself as anyone else.
