With these all-about-water facts to know and things to do, make discoveries you'll never forget about the hundreds of amazing things water does. Learn about water's floating properties with a game of apple-bobbing; refraction, with a bent straw; leaching, by making sun tea, temperature, by watching cold water sink. Watch the effect of gravity through whirlpools, buoyancy with a boat race, spattering with a droplet of paint, and flow with a quill pen. All these are things you can do with simple props -- more proof of how water is involved in almost everything you do.
