7 Exciting Things You Are Too Lazy to Google - Part2

Why do birds fly in V-formations?

First of all, they save their energy: the birds flying in the front row create special air swirls with their wings. Those flying in the back rows "catch" the swirls and conserve their energy. Second, such a formation helps all the birds at once see the leader, who always flies first.

Why is dust white against a black backdrop and black against a white one?

Actually, ordinary dust is gray. However, the tiny size of its particles prevents us from seeing its real color. We just spot if the specks are lighter or darker than the background.

Why do raccoons rinse their food?

Raccoons often get food from the water and its surroundings so there can be some ooze and algae that they try to clean off. Another reason is not so cute: this animal might kill its prey this way. Raccoons simply "rinse" the life out of it.

Where does toilet waste go on a plane?

When you press the flush button in the plane, a valve opens and sucks down the contents of the bowl. The contents are carried into a holding tank within seconds till it reaches its limit. A single storage tank can hold about 20 gallons of waste. Right after the plane lands, a service truck removes all the waste from the tanks.

Why does a brook babble?

The sound appears when air bubbles are captured by the stream of water and burst. This gives us a variety of sounds, which we call "babbling."

Why do clock hands move sunwise?

People had sundials before inventing the mechanic clock. The sun version had a pole for its shadow to move around the hour plate. Such a "hand" moved the same way as the sun across the sky during the day. In the Northern Hemisphere, the direction was from the left to the right. The mechanic version of the clock was invented there sometime later.

Why is the ring finger used for a blood test?

First, the thumbs and pinky fingers are closely connected to the wrist. If you get an infection, it can be distributed up through the arm. Consequently, they advise taking blood from all the fingers except the thumbs and pinky fingers. Second, the ring finger is the least painful. It "works" less than other fingers and has thinner skin. If you don’t use this finger often, the slight wound will heal quickly.
