My entry to Phipson's Spring Fling Contest; it's just something my friend and I built. With a good rubber band, it can fire 15 feet, meeting the contest requirements. Unfortunately, my neighbor doesn't have any cats that I know of.
About this creation
As the title says, it fires rubber bands.
It has a trigger (obviously).
It has a scope.
It even has a safety.
It can also fire multiple rubber bands.
Now lets bring forward the target.
It can also knock down larger objects.
Have you ever wondered why the Rebels lost the Battle of Hoth?
Quoting William Meng Thanks! And did you know that if you copy and paste "®", you can write it here? Or if you know unicode, you can hold down alt and press the code, which is "00ae". It's pretty cool.
I actually was aware of all that - I was simply much too lazy to attempt it... ;)
