Bathtub Science - Tapa blanda

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