SURPRISE-ASAURUS

Dinosaurs may be extinct, but that doesn’t mean they can’t surprise us every now and then. Case in point: this puzzle. Assemble its 500 pieces, then turn off the lights to see the prehistoric scene become a glow-in-the dark fossil site (with a special cameo by the asteroid that did them in). Consider framing it so your resident dino enthusiast can watch the transformation night after night.
