Great for booby trapping doors or dresser drawers..heh

I remember doing that, I think i'm gonna have to get my kids with that trick.

I've never tried using those for booby traps, but i'm still a fan of using these...

They can be improved (slighty) by pushing the paper cap pass the corrugation where it sits and adding 1 or 2 extra paper caps, if I ever get the chance to add an extre expolsive part I'll let you know the results (assuming I still have fingers to type with).

Fingers are always good
