Why don't you rig one of the gophers with the camera, and put a little
suicide vest on him? Then you can watch him go down the hole, or to show up
for a gopher hoe-down, and blow up a whole pack of the little suckers at
once.

If you rig him with a receiver and a speaker, you can even shout "Allah
akbar!" just before you push the button.

You could make kits for the things and sell them through ebay. These should
sell big in flyover country.

Nah, propane down the hole is more fun!
