Last summer I filled a 2 liter plastic soda botlle partially full of
warm tap water, about 3-4" worth. I then dumped in a few chunks of
dry ice. We then screwed on the top of the bottle TIGHT and ran like 
crazy.

After 2-3 minutes of strange noises (plastic under stress) the container
exploded with a huge mist of water (probably ice crystals due to the huge
drop in pressure). The noise was deafening to say the least and I was worried
it would shatter nearby windows.

My 10year old son LOVED it.

The largest piece we found was a piece 1" long by 1/2" long - who
knows where the rest of it went?

If you do it yourself, a few cautions are in order:
1-Only do this in plastic bottles. Glass or metal containers could easily kill
  you or anyone in the area. 
2-The time delay is unpredictable and very variable. There is simply no way to
  predict when it will detonate so RUN away and STAY away until it detonates.
3-Dry ice is dangerous to touch or hold. Use gloves or spoons. If it touches
  your skin, it will damage it due to the extreme cold (-112F).
4-Its LOUD!


Be careful out there...
