We Dare You! by Vicki Cobb and Kathy Darling

Slime Mold Races, Electronic Spit, and Erupting Soap -- they're irresistible projects that sneak in science lessons for your kids, and this collection by Vicki Cobb and Kathy Darling, subtitled "Hundreds of Fun Science Bets, Challenges, and Experiments You Can Do at Home," is full of 'em. We got sucked in, too; who wouldn't want to know how to tie a knot in a bone, burn a candle under water, and hypnotize a frog?
