1. Apply thread tape to threads on the cast iron bomb cap
2. Fill the ice bomb full of water and securely screw the lid shut with the pliers. To insure that there is no air inside of the ice bomb fill a bucket of water and tighten the bomb while it is submerged
3. Try to get all the air out
4. Cut the top off a 2L pop bottle so it creates a container for the liquid nitrogen (make it as tall as possible)
5. Place bomb inside the container and add liquid nitrogen until the container is full (more is better so as to make sure the bomb explodes)
6. Place the protective cover over the apparatus and wait for the explosion.
