The first couple of times the boys used too much force and the glass was pushed over, or the egg went flying across the yard as they hit the toilet roll as well. This is why we did it outside. Amazingly the egg lasted the 10 times that this experiment was tried. Some have actually taken it further and used 3,4 and even 5 eggs/toilet rolls and glasses. We didn’t, as we didn’t have that many eggs at the time.This amazing egg experiment in based on Isaac Newton’s Law of Motion (also known as the Law of Inertia).“Every object in a state of rest or uniform motion in a straight line tends to remain in that state of motion unless an external force is applied to it.”
Basically objects keep doing what they are doing, whether it be rest or motion, until something else exerts force onto it.
What you need:
- pie plate
- toilet roll
- raw egg
The egg should plop into the water.
