The contents of this very large box could be found at any dollar store, and can fit in 2 ziplock sandwhich bags.The anometer is a joke. It would take a 10 mph wind just to budge it, and they did not include the 9v battery. The phrase "Craker Jack box" comes to mind.The only saving grace for my $20 investment was that my 9 yo daughter seems really interested in doing the experiments. But we'll have to make a trip to the dollar or craft stores to get what is needed for most of the experiements.Nice concept, grossly overpriced with cheesey parts.I would gladly have paid 5 times the price to find a quality science weather kit, but they don't exist.
