This entertaining video demonstrates how to make a bottle rocket using tape, paper napkins, Mentos, and Diet Coke or Coke Zero. Try at your own risk! Make a pouch with the paper napkin. Put the Mentos in the pouch and roll the napkin with the Mentos into a tube shape. Open the plastic bottle of Diet Coke or Coke Zero. Place the tube in the top of the bottle, but don't let the Mentos make contact with the soda. Keep the napkin/Mentos tube stuck tightly in the top of the bottle. Re-attach the bottle cap. Shake the bottle for several minutes. Throw the bottle in the air so that it will come down with a enough force to make it bounce pretty hard. When it hits the ground, it should launch itself into the air shooting out Coke!
