No kidding? I wouldn't have thought so, but I believe you. In any case,
Alka-Seltzer is much easier to aquire than dry ice.

Gave us:

Much simpler: Put a little dry ice in a plastic drink bottle, like
bottle
water comes in.

Add an inch or so of water. Cap tightly. Run away!

The 1/2 liter bottle will swell up to the size of a football before
exploding with a bang reminiscent of shotgun blast...very loud.
Sometimes
it takes a few minutes, sometimes longer. If you don't use enough dry
ice,
it only swells. Don't touch it, it could still blow. Throw a rock at it
first, or just leave it alone..


Much much simpler:

Heated water and Alka-Seltzer tablets. Same boom!

Don't have to wait as long.
