481. How does the blood type work?

The test to determine your blood group is called ABO typing. Your blood sample is mixed with antibodies against type A and B blood. Then, the sample is checked to see whether or not the blood cells stick together. If blood cells stick together, it means the blood reacted with one of the antibodies.

Blood typing procedure:

•Mix! First mix the patient's blood with three different reagents including either of the three different antibodies, A, B or Rh antibodies!

•Look for agglutination!

•Then you take a look at what has happened.

•Figure out the ABO blood group!

•Figure out the Rh blood group!

•Figure out the blood type!

478. Why do pirates cover one of their eyes?

Some assume pirates wore eye patches to cover a missing eye or an eye that was wounded in battle, but in fact, an eye patch was more likely to be used to condition the eye so the pirate could fight in the dark.
It takes an average human eye about 25 minutes to fully adapt from bright sunlight to seeing in complete darkness—if a pirate was fighting on deck in the light, then had to go under the deck to fight downstairs where it is usually pretty dark, that would be a long time to go without being able to see. The eye patch could be used to prepare one eye to see in the dark, so when they would go below deck they could swap over the eye patch from one eye to the other and see with the eye that has already adjusted to low light conditions. This would allow them to instantly in the dark.
 
477. How do Pay Phones Work ?

Pay phones, or coin phones, are activated by the weight of the coin as it is inserted. The coin activates a pulse, and the pulse starts the dial tone of the phone. Each pay phone is programed with calling rates and fees.
An electronic device monitoring the current rates for local and long-distance calling is installed in the payphone while it is being made. This device also contains information about calling cards and collect call data.
When the dialer attempts to make a call, the phone will calculate the amount of money needed for the call based on the length of time the dialer wants to talk. As the time ends, a voice will request additional money to be deposited to continue the call. If money is not deposited, the phone will automatically disconnect the call when the deposited money runs out.
 
475. Can Rainbows be full circles?

Yes! Rainbows can be full circles. However, the observer normally sees only an arc formed by illuminated droplets above the ground, and centred on a line from the sun to the observer's eye.
In a primary rainbow, the arc shows red on the outer part and violet on the inner side. This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.
In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, with red on the inner side of the arc.
