Balloon birthday surprise aka trick Saw it on Pinterest and had to try it for my daughters 12th bday. Had a horrible time blowing up the balloons because I was laughing too hard imagining her reaction!!!
A balloon avalanche as a birthday morning surprise. I did this for my boyfriend's 19th birthday and he was shocked! It was the first time I could finally pull off a surprise without him knowing and he loved it.
