Bending Water

Good afternoon scientists! We just bent water using a comb and you can too! Try bending water with your little scientist today.

Materials

Bending Water (2)

Comb

Cloth (Fluffy, Cotton Works)

Sink

Investigation

  1. Turn the sink faucet onto the lowest setting with a continuous stream. Rub the cloth on one end of your comb’s teeth vigorously for 30-45 seconds.Bending Water (8)
  2. Carefully remove comb from cloth without touching the teeth of the comb. Hold the comb so the the teeth of the comb are close but not touching the water then slowly move the comb away from the water. ** note if the water doesn’t bend you need to “charge” the comb with more static electricity and try again.

Talking Points

In this experiment we used static electricity to bend the water.

Static electricity is an excess electric charge that is made by friction (force of two materials rubbing against one another) it is also static or still until it can be released. Static can be released by completing an electric current (movement of certain objects like paper, hair and water) or by a electric discharge (zap or shock).

In our experiment when we held the “charged” comb near the water. An electric current occurred pulling the water molecules towards the teeth of the comb, this is what actually caused the water to bend.
