629. What do astronauts drink?

Silly question. We know it's water!

But then comes the difficult question: how do they have large amount of water supplies for months?

Recycle is the answer.
The space station has a complex water system that squeezes every last drop of available, drinkable liquid out of the environment. In simple terms, astronauts are drinking a filtered mixture that includes recycled shower water, sweat, and urine. This ensures they have continous supply of water during their missions.
Oh, and don't worry. The processed water is super clean and "tasted like bottled water".

The colors of a dog's eyeshine aren't limited to red and green, either. They can be all shades of blue, orange, yellow, turquoise or even violet.

62. Can you feel pain in your brain?

There are no pain receptors in the brain itself. But he meninges (coverings around the brain), periosteum (coverings on the bones), and the scalp all have pain receptors. Surgery can be done on the brain and technically the brain does not feel that pain. With that said, the brain is the tool we use to detect pain.
