Materials Required:
l Sheet of typing paper
l Rubber band
l Book
Procedure:
- Roll a single sheet of typing paper into a tube and slip a rubber band around it.
- Stand the tube on end on a flat surface. Carefully place a book on top of the tube and you will see that the paper supports the weight of the book.
This Is What Happens:
A tube is a shape that has much more strength than a flat object. This allows you to place the book on top of the paper without crushing it. Pillars are a type of tube shape, and they are used in some buildings to hold up their heavy weight.
