Some of the smallest things on earth are surrounding us all the time, and we don’t even know it. Check out the following totally true teeny tiny things.
~ the smallest nest is built by the vervain hummingbird. It’s the size of half a walnut shell!
~ you have 6 million tiny cones in each eye. These cells make you see colour.
~ a person with a cold sneezes 40,000 germ droplets into the air.
~ the teeny thread of a silk worm’s cacoon, when unraveld, can be over half a mile (1 km) in length.
~ a trillion metric tons of the world’s water evaporates each day in the sun. Luckily, it all returns again in rain.
~ light is the fastest thing in the universe. It travels at more than 180,000 miles (300,000 km) per hour.
~ a glittering polar fog called, Diamond Dust, is made up of tiny ice crystals.
~ lightweight atoms called, Helium, escape easily – that’s why your balloons go down so quickly.
