Description: This demonstration shows that a charged rod can deflect a stream of water.
- Rod and Fur.
- Rubber hose connected to the sink.
- A stand and finger clip to hold the hose above the sink.
- Attach the hose to the sink.
- Put the end of the hose in a clap on a stand and aim it to the sink.
- Test the water to make sure it goes in the sink and the hose stays in the clamp (very important).
- Turn on the water to get a very small (almost steady) stream of water.
- Bring a neutral rod near the stream and note that nothing happens.
- Charge the rod using the fur and place it near the water stream on the side.
- The water will become attracted to the rod and the stream will bend toward the rod.
Note: Works better with a small stream of water.
After a little while, the rod discharges to the water, and the stream will not bend as much.
