Frozen Shaving Cream Bomb

The frozen shaving cream bomb is another practical joke that involves making a mess with shaving cream using unconventional methods. It will allow you to completely fill your victim's mailbox (or other small space, such as a drawer) with shaving cream. This method only requires the prankster to be at the mailbox for less than 10 seconds and is much faster than emptying a can of shaving foam into the box. This prank relies on the fact that shaving cream is highly compressed inside of the can and expands greatly when exposed to air.

Here is how it works:

1) Place a can of shaving cream (foam, not gel) in the freezer for at least one week. If you have access to a very low temperature liquid, such as liquid nitrogen, you can freeze the shaving cream much faster by dipping the can into the liquid nitrogen. Regardless, it is crucial that the shaving cream inside of the can is frozen solid.

2) Get a cooler filled with ice, or dry ice (if available) to transport the shaving cream can and keep it cold and frozen. Dry ice is often available at the grocery store if you ask the butcher. As long as the shaving cream remains frozen, the foam will remain compressed and will not expand.

3) Get a tool that will allow you to cut open the can of shaving cream to reveal the frozen solid cylinder of shaving cream inside. Cut open the can so the frozen chunk of shaving cream is readily available to quickly place in the victim's mailbox or drawer.

4) Drive up to the victim's mailbox and quickly drop the frozen cylinder of shaving foam into the box and drive away. It is a good idea to do this at nighttime so you have some cover from the darkness and so that it is less likely that there will be mail in the box.

5) Wait. Once the frozen chunk of shaving foam is in the victim's mailbox or drawer, it will begin to dethaw and begin to expand and completely fill the mailbox or the drawer. It is likely that the shaving cream will expand so much that it will begin to ooze out of the seams of the box.
