Materials Required:
l Empty mayonnaise jar
l Uncooked rice
l Knife with blunt, wide blade, such as a cake knife
Procedure:
- Fill the empty mayonnaise jar with uncooked rice and pack it down firmly. Add more rice until it’s even with the top of the jar.
- Poke the blunt knife into the rice several times to a depth of about 2 inches. Then jab the knife in firmly, about 6 inches deep.
- Now slowly pull the knife upward. You will lift the jar of rice.
This Is What Happens:
The rice grains, which fill the jar, have many air spaces between them. As you poke the knife into these grains, they become tightly packed. When you finally jab the knife deeply, the rice is pushed against the blade and holds it in place. This gripping force enables you to lift the entire jar as you raise the knife.
