Pow! Science! makes good on its one-two exclamation-point punch with a vast collection of toys, games, and educational kits for budding paleontologists, potential physicists, and future-mad scientists. Specialty items include the wizard stick ($15.99), which shoots genuine fog at the pull of a trigger, and the electro chemistry wiz experiment set ($17.85, ages 5+), which potentially lets young scientists invent a new type of adhesive that, unlike glue or thumbtacks, isn’t mistaken for food. The smart lab car design studio ($19.89, ages 7+) gives grade-school gearheads a pre-license outlet for their vehicular devotion, and Sea-Monkeys ($16.49) teach kids that life is created by adding dry powder to water.
