How to stand on eggs
 
  1. Place three chairs around the 2 open cartons of eggs
  2. Sit on the middle chair and place your hands on the the other 2 chairs.
  3. Put your 1 foot on the rows of eggs on the each of egg cartons
  4. Supporting your weight with the two chairs, carefully raise yourself upright so that you slowly bring more weight onto the eggs until you are completely standing on them without support!
Measure the weight eggs can support
 
  1. Place the wooden board over both the egg cartons.
  2. How much weight can you place on the board before the egg shells crack?

Egg shells are very strong if they are compressed. The curved shape of the egg shell allows force to be spread horizontally and vertically throughout the shell

You can think of an egg shell as being like a 360 degree arched bridge. Engineers have known about the strength of arches for thousands of years. They are very stable and allow building structures to support a lot of weight.

Find out how arched bridges and others work.
