Have you ever checked out Sam Barros and PowerlabsThis is such a cool site.  Every once in a while someone links one of his experiments from Slashdot, and it reminds me how cool it really is.

Exploded CDThe most recent experiments involved using a Dremel router to spin CDs beyond their structural limit.  "A high speed rotating CD Rom is a bomb ready to explode and will send razor sharp plastic shrapnel in all directions when least expected."

If you're thinking this guy would make a fun neighbor, then you would really like his experiments with homemade cannons.  "The culminating point of this project was loading 30 grams of a potassium bromate/sugar/sulfur pyrotechnic mixture into the cannon with a 200 grams nitrocellulose hexanitrate propellant charge, and ramming the golf ball into it with a tight fitting cotton sabot."  He shot the golf ball over 6 miles.  Come to think of it, he wouldn't have to be your neighbor.

They hold the record for fastest object accelerated of a significant mass..."

Oh, yeah, Sam is 18, a freshman at Michigan Tech.  Whew.
