Happy Birthday avalanche! Close bedroom door trap balloons against the door frame when the person opens their door the next morning, its raining balloons,
YES PLEASE Money Balloons - a cool way to present money as a gift, esp for a young person (as opposed to a boring check in a card). I have a friend whose parents blow up a balloon and put a one dollar bill in it and have the number of balloons for how old their kid is on their birthday and then after they open their presents they can pop open the balloon and get their $. very cute.
Two large garbage bags + painter's tape + balloons = balloon avalanche. How awesome would this be to do the morning of a kids birthday!
