Have you ever heard that the short is less likely to get knocked over? Do you know why? It is all about the center of gravity. This experiment Hammer Ruler Balancing Trick we going to show is the best demonstration of the center of gravity. And, it looks magic.
Age: 5+ Time: < 10mins
Safety
- Adult supervision.
- Be careful, the hammer may fall to hurt your feet.
Materials List
- Hammer
- Rope (use a stronger one to avoid being broken)

Can you think of something to replace the hammer? It requires what kind of future?Scientific Description
The center of gravity of an object is the point that averages the location of the weight of an object and all sides are in balance. When the point of the center of gravity and point of the connection share a plumb line, the object is balanced and will stand still. We can see the rope, ruler, and hammer as a system and the center of gravity is within the connection between ruler and table. So the ruler keeps standing on just one end.Extensions
