For Josh's birthday this year we put money in the form of quarters inside of water balloons. Yup, 1 quarter per balloon. I had seen on Pinterest about putting dollar bills inside of balloons, but I wasn't sure how to get a dollar bill inside of a water balloon and so I decided putting quarters in water balloons. I couldn't get the quarters in without ripping them, so Dave sat there and did them all. It was just a fun way to give money.
