Even Einstein started somewhere, so who's to say your little genius-to-be won't find inspiration in the bath? Gather up your gear: floating toys, fluffy towels, warm tub, favorite little lab partner (may take multiple attempts). Place tiny tot in the tub (note water displacement), and proceed to explore buoyancy, gravity, and evaporation. Now it's time to make waves and see that third law of motion in action. Go, baby, go! Wait, hold on . . . Stop, baby, stop! In a bright, graphic board book leavened with dry humor, photos of happy tykes and a tongue-in-cheek running dialogue are sprinkled with factual asides that define basic concepts of physics. So don your protective goggles--with a bathtub as a lab bench, your precocious little one can master physics every day!
