Review on ✨ Sparkling Fun: Explore the Magic of Constructive Playthings 00010 Light Crystal by Gene Taylor

I wake up on a sunny Saturday morning to a happy squeaking noise. When I enter our living room, I see my children dancing and trying to "catch" the rainbow. This prism was a gift from Santa, hidden in my middle child's stocking. I put it on the south facing windowsill in our living room and every sunny day I get a rainbow. I don't understand why there are negative reviews for this product. Works absolutely perfectly. Maybe ours have Christmas magic, and that's why ours work, but they don't.
