"Whenever we have play dates, the ball pit is one of the most popular hangouts in the playroom. Seriously the kids LOVE it! We've had this ball pit since Jake was 6 months old and it's still one of his favorite toys. You can easily make your own with an inflatable swimming pool and pit balls (we used 200). "
Great idea for a backyard party. These are kiddie pools stacked. I think it is a bucket between the layers. This could go with any party. Great place to keep the drinks cold. Make sure that it is stable.
