How to make a Pokeball Piñata for a Pokemon birthday party. How said piñatas are only fun for the kids? My son and I had a lot of fun during the piñata making. It was very simple to make (the paper machê I used was 1 part of white flour to 1 part of water) and durable. After watching a few videos on YouTube we decided to make 6 layers of paper. I feel that it was a good amount to outlast 10 year old boy's hit.
