I am hanging out along side the pool sitting on a inflatable air mattress and I have a bunch of plastic bags to pop. I blow and twist the bags and slap to pop them but then I also discover that IF i put some pool water in the plastic bag as well as air and then pop it, I get a big splash and a loud pop. Awesome! I enjoy this so I decide to switch back and forth from only air to air and water in the bags to slap to pop them. What fun along side the pool with my lil bags. I have to do this again soon!! *MP4 Format*
