Rubber Band Canon V2
This is an adaption of the Rubber Band Canon. This version has a lot more power. Each band is stretched to its limit to provide the most powerful impact. Unlike the original Rubber Band Canon, there are 13 bands on this version. The pain level from this device is considerably higher than that of the original Rubber Band Canon.
This version uses the small rubber bands that people use to tie their hair back. I chose this type of rubber band because of how easy they are to find.
As these bands are pulled so far they will break more often. Therefore this version is designed to make the bands very easy to replace. There are no bolts to undo, just remove the base cap pull out a pin and replace a band. There is even a space under the base cap to store spare bands.
