If you’re ever out of gift ideas, check out Grand Illusions Toy Shop. They’ve honestly got unique and timeless gifts for Dad or anyone you can think of that enjoys illusions, scientific principles, and just generally neat objects. Even if you don’t buy, they do a good job of explaining the principles behind their toys and sharing video demonstrations. Why Boing Boing hasn’t found this yet, I’m not sure.
Grand Illusions used to sell a pseudoscope, a device that makes things look inside out, for a price that I couldn’t justify for a toy. Luckily someone’s come up with instructions on how to make a pseudoscope.
