I found the original pin HERE.
Items Needed:Water Bottle
Paper to cut into scraps
Cut the top off the water bottle with some scissors
Put the masking tape around the cut edge. This helps keep kids from cutting their fingers!
Put the balloon on the top of the bottle, move it down so it is a bit shorter on the end (does this make sense!?)
Cut little papers, use marshmallows or whatever you would like and place inside the balloon.
Pull back the balloon and the confetti sprays out everywhere!
