Materials Required:
l Brown paper bag
l Scissors
l Window
l Peanut
Procedure:
- Cut open a brown paper bag, such as a shopping bag. Lay the flat piece against a window.
- Rub a peanut, without its shell, firmly on the bag. Move the nut back and forth several times over the same area. Soon you will see light coming through the rubbed space.
This Is What Happens:
Did you know that peanuts contain a large amount of fat? When you rub the peanut on the bag, the bag absorbs some of this fat, which soon spreads into the paper and fills in the spaces between the fibers. This allows light to pass easily through the paper.
