Materials Required:
- Sheet of typing paper
- Rubber band
- Book
Procedure:
- Roll a single sheet of
typing paper into a tube
and slip a rubber band around it. - Let the tube stand 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 have the shape like that of a tube, and they are used in some buildings for holding up their heavy weight.
