The next questions

Q: A can of pop just exploded in my car. Can you tell me how that happened?
A: If you shake it, the can could explode. If it was very hot outside, then that would have made it explode. But no one knows why.

Q: How can it rain in 26 degree weather?
A: The atmosphere is made of different layers and different temperatures. It could be 22 degrees up high, and 32 degrees lower.  When a drop of rain passes through these layers, it can freeze and unfreeze. If it was 26 degrees on the ground, and 37 degrees a little bit higher, then the raindrop would not have enough time to freeze.

  1. If I have a bottle of water filled to 500ML and I keep it open, how much water will evaporate in 1 month?

  2. Thanks Laryn. We are trying this experiment at home in the kitchen. It is evaporating slowly. We will keep you posted. :)
