1. The Fuse:
Punch a hole near the bottom of an empty 10,5-ounce can (the Campbell’s Soup variety is perfect) and insert a 6-inch fuse from the hobby shop.
2. The Explosives:
Sprinkle in 1 tea-spoon of black or smokeless powder (available at Wal-Mart). Then cover it with a disc-shaped piece of tissue paper.
3. The Fuel:
Fill the rest of the can with Cremore, the highly flammable powdered nondairy creamer. Make sure it’s well sifted and not clumpy.
4. The Show:
At dusk, gather some friends, light the fuse, and run back at least 25 feet. Your creation will explode in a 4- to 6-foot ball of flames.
