Review: Follow the instructions and these work great. I used these for a STEM presentation for K-8th graders. They loved them. Offers an opportunity to teach Bernoulli's Principle.
Review: I love Steve Spanagler products. These are great fun. It only takes one breath to inflate those bags. They are big which kids like. My grandson loves them. I wish he still sold the giant windbag that is about 20 feet. It flies in the air. You need a string so you don't lose it. These are a great alternative though. The kids had hours of fun. Great buy!
