Urban legends and the Internet are good starting points.
If you get a chance, be sure to catch an old episode where they blew up an 8 or 10 yard transit mixer with 850 pounds of high explosives.
It doesn't get much better than that.
That one was cool, but a few weeks ago they were trying to make diamonds. They finally went to a mining school where they set off a concentrated explosion with 5000 lbs of explosives. It was deemed the largest explosion in Mythbuster history!
