Some of the following may not have the fire-power you would like but we say give them a try and, if you want, modify them. They are truly interesting and if all it costs is a lighter and some popsicle sticks – we say give it a try!

Our favorite is the hand zapper or a taser! While the other two may be fine for entertaining games we cannot see them killing an animal for food or stopping a serious predator! However, the taser, if it is hooked up right, could really give an assailant a shock should they make a move on you.

We can picture a man or woman in the city, having something like this wired up under their coat. If you are smart you will not get in their way!

In the end, we will all need to do what we can to keep us safe and we like inventors like this that give us great ideas!
