Totally True Teeny Tiny Tuesday

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.

Can you think of anything else that is teeny tiny, perhaps, a flea? Let me know what you come up with by leaving a comment.
