This is the science set packed with seemingly devilish experiments inspired by "The Dangerous Book for Boys." Presented as a collection of nostalgic activities, this set contains more than 60 chemistry and electronics experiments that educate boys and girls alike without their ever realizing it. Children will revel in the creation of invisible ink, slime, joy buzzers, and homemade light bulbs, but they'll also pick up edifying insights about elements, chemical bonding, and logical circuits. Younger scientists will find basic experiments to entertain them, while older children can dig into meatier pursuits that require more materials and diligence, accompanied by instructive supporting essays. The set includes safety goggles, assorted tools, and two illustrated 32-page instruction booklets. Requires two AA batteries, one 9-volt battery, and one button battery. Ages 8 and up. Box: 4 1/2" H x 10 1/2" W x 10 1/2" D. (1 1/2 lbs.)
