Answer 1

Hi. Try this one. You hold a crisp dollar bill with two fingers at the end. Put two fingers from your other hand near the face on the bill. You can drop the bill and catch it ALL the time. Now have someone else put THEIR fingers near the face while YOU still hold the end. They will almost NEVER catch the bill. It demonstrates that the bill accelerates faster than most people can react to, but since you KNOW when you will drop it, you will catch it. (This is a secret, so tell no one, OK?) You can talk about nerve signal transmission and biology, gravity, mass, etc., but tell no one the secret!
