This is, hands down, the most amazing bubble machine I've ever seen. I grabbed it at Sam's Club today and it brought every kid in the neighborhood running to our yard. 👏 The only down side was removing the 8 miniature screws on the fort-knox battery compartment and tracking down 10 AA batteries. Other than that minor annoyance, this $15 purchase has been totally worth it. It's called the Gazillion Whirlwind Party. Ours came with a big stash of bubble solution but if yours doesn't, you'll want to buy some because it went through solution pretty quickly. It got mixed reviews on Amazon but my kids loved it!
