Tips

  • Shake for best results. Sometimes it will not work with just pulling the ring.
  • Make sure that when you create the baking soda part, you don't make the tape part too long. This would make the toilet paper/baking soda sag in vinegar and it would explode pre-maturely.
  • If the bomb does not explode after being thrown, open it with the cap facing away from you.

Warnings

  • Do not throw at peoples faces or try to cause harm to them or their property.
  • Do not throw at animals. Although you may be playing it could cause harm to the animal.
  • Please do not throw at personal property or in public places.
