Snap the hand together and take hold with flexing fingers and opposable thumb! This pull-trigger skeletal hand works like a human hand but without skin blocking the view. It's far more entertaining! Experiments and comparisons offer a first-hand look at how we grip, grab, and grasp--and that's just the beginning. Lefty or righty, it's handled here! Read all about it! From flexors and thenars to extensors, there's so much to know about this most-used and under-celebrated body part! Hands-down, kids will find this a worthy read. Written by Melissa Stewart. 24 pages. Full colour. 5 experiments. Ages 8 and up.
