Ag Experiment #2 Brazil Nut
This experiment will show you why the largest nuts in a can of mixed nuts always seem to come to the top.
You will need:
- 1 - cup of small dry beans, such as black beans, soybeans or navy beans
- 1 - cup of medium-sized dry beans, such as kidney beans or pinto beans
- 1 - cup of large dry beans, such as lima beans or large fava beans
- 1 - large glass jar (holds at least 6 cups)
- Pour the large beans into the jar, then the medium-sized ones, then the small ones.
- Look at the side of the jar. The beans will be more or less separated into layers, with a little mixing together in places.
- Put the jar on a table and start shaking it gently from side to side. Watch what the beans do as you shake the jar.
- Do the experiment 2 or 3 times to observe the action.
Does this explain why the large nuts are at the top of a jar or can of mixed nuts?
