Bathtub Science

Kids love the tub--and it makes a really cool "laboratory” for carrying out experiments that are gallons of fun. Find out why some toys sink but rubber ducky always floats. Make a "wave machine,” a water cannon that blasts mind-boggling explosions of liquid; zippy hydroplanes--or peer through periscopes and prepare perfect bubble solution. Every page bursts with brilliant drawings, and loads of photographs that display the entire process.
