Surprise friends and family with this cute little prank! All you need is a plastic cup with the bottom cut off and a balloon that is tied off at the bottom with the tip top cut off. Stretch and tape the balloon on to the bottom of the cup (this will act as a sling shot). Next, make a cute little spider (or eyeball, ghost, etc) out of a small foam ball and pipe cleaners. Place the critter in the cup, pull the balloon tie and let go – voila you have a cute and creepy spider jump scare!
