I sent you this comment already but i think it didn't go through.

Have you ever thought about making a (NON-destructive) explosive? I once made a (non-exploding) sandwich-bag bomb. Try to see if you can think of an idea.

You could fill the bag with vinigar and baking soda, which builds up pressure, making it explode.

PS. If you try this make sure to zip the bag quickly after you add the soda!
