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 30 chemistry experiments that educate boys and girls alike without their ever realizing it. Children will revel in the creation of invisible ink, slime, but they’ll also pick up edifying insights about elements and chemical bonding. 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. Ages 8 and up. Box: 4 1/2" H x 10 1/2" W x 10 1/2" D. (1 1/2 lbs.)
