| ===== Purpose ===== | ===== Purpose ===== | ||
| - | + | To demonstrate how the density of a material affects it's buoyancy. Also shows how the idea of buoyancy can apply in media other than water. | |

| ===== Setup ===== | ===== Setup ===== | ||
| - | + | - Bury ping pong ball deep into the beans. | |
| - | - Insert ping pong ball deep into the beans. | + | - Place steel ball on top of the beans. |
| - | - Place steel sphere on top of the beans. | + | - Next, gently shake the bowl. As you do this the ping pong ball will rise to the surface and the steel ball will sink to the bottom. This shows that the density of the beans is somewhere between that of the two balls. |
| - | - Shake bowl and sphere moves to bottom and ping pong ball moves to the top. | + | |
| - | - The density of the beans is somewhere in between that of the steel ball and ping pong ball. Updated on 06/10/13 | + | |
