Battery Hand Gun/cannon
Ok, so I'm planning to make this instructable, it shoots out batteries at incredible velocities. It's fairly dangerous. It involves the use of match powder. However, it has come to my concern that people might worry or even hate me for posting this instructable. So I'm going to ask users on this instuctable if yes or no, they want me to post it. Here's a picture of the damage it can make. The first picture shows the side where the battery first stuck into the 3/4 inch thick wood, the second shows the other side where the battery left. So, do you want me to post it?
