Discover the strength of a dome

Some of the strongest shapes in nature are curves and domes. Think of the ancient temples, churches and buildings that are still standing after hundreds of years. Explore why a dome is so strong with your kids and help them learn about these cool scientific facts.

What you need:

  • Four empty eggshells
  • Scissors
  • Masking tape
  • Medium-sized books

Number of players:


Tape some masking tape around the middle of one eggshell.

Cut the eggshell in half through the masking tape, leaving four eggshell halves.

Place the eggshells dome up in a rectangle sized just a bit smaller than one of your books.

Carefully place a book on the eggshells. The eggs will hold it without cracking.

Keep adding books until the eggshells crack. How many books can they support?
