Q.What is the world record for staying under water
A.The world record for the longest time underwater without taking a breath is an incredible 19m 21s, held by Peter Colat of Switzerland since Feb 2010.
A.Fish don't sleep like mammals but rest & save energy in a still, daydream-like state. With no eyelids, they don't shut their eyes & stay alert to danger.
Q.When you're in the bath a long time your fingers and toes go all wrinkley and weird. Why doesn't the rest of the skin on your body like your arms etc wrinkle?
A.The fingertips and toes wrinkle when in the bath because water seeps through callus skin (skin hardened by work) into the dead cells, making them swell.
Q.Where does the water go when the tides goes out x
A.When the tide is out at one location, it is high tide in other places. The total amount of water in the oceans stays the same. All coastlines have tides.
