Fill water glass about 3/4 way full, place pie tin on top of water glass, place paper tube on top of pie tin and directly over the whole of the water glass. then hit the pie tin from the side very quickly.
Why does the egg fall right into the glass?
This was answered by Sir Isaac Newton’s First Law of Motion, which states that an object at rest remains at rest and an object in motion stays in motion with the same velocity unless acted upon by an unbalanced force.
Because the egg is not moving at the beginning, it wants to stay that way.
When the pan is knocked with my hand, the raised edge knocks off the paper roll.
When the support of the egg is removed, gravity applies a net downward force that pulls the egg straight down. The egg then drops right into the glass. TADA!
