Answer:
If I told you that we were going to fill a glass with water, and then turn it upside down without spilling the water, you probably won’t believe me. But that is exactly what we are going to do during this simple science experiment.
Both kids and adults will be amazed by this experiment that appears to defy gravity. Just be sure to do it over a sink or large container lest you accidentally make a BIG wet mess.
