    Nice! Quite coincidentally, it looks like my catapult too! Except, I wish I came up with this idea. Not only is it more powerful (at least for me), but it is smaller. Love it.

    Instead of leaving the rubber bands the way they are, put the arm through the 2 of them, and twist them once or twice before putting the whole thing back, should get more power
