Bet a friend that you can balance a pile of books on egg shells without
crushing them. (Ask your mum or dad to save up some egg shells for this
trick.) |

1. Wrap masking tape around the broken edge of each shell and
cut the edge so that the shell will sit flat.
2. Place the egg shells so that they will support the four corners of the
books.
3. Carefully balance the books one by one on top. How many can you pile
on before the egg shells start to crack?
How the trick works: The curved shape of egg shells passes the weight of
the books down and over the entire shell. This makes the egg shells able to
support more weight. |
