Here is something we do for backyard birthdays. I randomly by small goddies toys from the party stores. Then hubby and I stuff them into the balloons, he blows them up. At the party, we bring all the prize filled balloons into the yard, hand the kids out a bag, or pail, something to put their loot in, and what they have to do is sit on the ballons on the grass, and pop them, then they get the prize!!! With 8 kids or so doing it at once, it is really a hoot to watch, and they love doing and it and earning their prizes!!! Our last party, I did about 80 balloons!!!
