Cool product. For the money its neat and tcheaes a science principle. Just treat it with care and it should last a while. A really low price and demonstrates the Bernoulli effect. COOL. "

This is a cool little gagdet that kids enjoy playing with for a short period of time. Its main problem is its fragility the one we bought broke literally before we left the store. We glued it back together at home and it lasted for a while, but then it broke again. In sum, it's fun for a little while about as long as it will take to break. "
