Finished! Now have fun launching them. To launch, put the skewer on the ground and pull down the straw. When you let go, the fun jumper should go flying into the air. You can even tape a paper airplane to it or you can launch it from your hand! You can modify it to jump higher also. The length of the skewer, length of the straw, and tightness of the rubberband effect how high it jumps. Just be careful and don't launch it towards anyones eyes.
