The strength of an arch was proven in our science experiment today. We carefully cracked four eggs at one end and poured them into a bowl to scramble and eat for lunch.
Then we stuck tape around the center of each egg and carefully cracked the open end off until we reached the tape. This allowed the eggs to sit on their own with the arch side up.
Next, we place all four egg shells on the counter and placed books on them until the eggs completely cracked.
Our eggs held over 9 1/2 pounds of books!
