Explosive Boiling

Take a glass of water and heat it in the microwave until the water almost boils. Then take out the glass and put any small object into it, the water will boil when it comes into contact with outside objects.

It's all about the microwave where the water doesn't boil, it's structured. If you heat water on a gas or conventional stove this effect will not happen.
