    Has a bubble in it. Not free shipping

    Meh. I had one and accidentally broke it. Bought from Sci-Supply as it said free shipping, but it wasn’t. I asked why, and they said it’s not eligible, despite the product page saying free shipping. I don’t get this monkey business with Amazon, so back there I go. You had a shot, Sci-Supply, and blew it. Response from Sci-Supply: Craziness! We are still cheaper than Amazon with the price of shipping added! Our website clearly states free shipping with a $39 order in no uncertain terms.

    My daughter is under ten and so curious about the world. I wanted a tool to help explain forces like gravity and those that have a powerful effect but can't be seen. I love having gadgets around the house and was so glad to discover this site, Shipping & delivery were lightening fast!
