This is a fun experiment for kids, especially if they’ve never seen it before. You’ll get the best results by doing it on someone who has long hair without any hair spray or styling product in it.
How to Make Your Hair Stand on End Video
- Sweater or T-shirt
- Someone with Long Hair (preferably without hair spray or styling product in it)
Step 1 – Begin by blowing up a balloon. Wave the balloon about 2-3 inches above the person’s head to show them that nothing happens.
Step 2 – Next, rub the balloon back and forth on a sweater or t-shirt. Do this for 5-10 seconds.
Step 3 – Now wave the balloon about 2-3 inches above the person’s head, and watch what happens this time?
How Does the Experiment Work?
Most objects do not have a positive or negative charge, they are neutral. Some objects, like balloons, have the ability to become charged. At the beginning of the experiment, when you wave the balloon over the person’s hair, the uncharged (neutral) balloon does not attract the person’s hair.
By rubbing the balloon on your shirt, you are giving it an electrical charge. Rubbing the balloon allows electrons from your shirt to move onto the balloon. This gaining of electrons gives the balloon an overall negative charge. When you wave the balloon over the person’s hair now, it stands on end. This is because the negative charges of the balloon attract the positive charges of the person’s hair. Unlike electric charges attract each other.
The outcome of this experiment is a result of static electricity. Static electricity is a stationary (not moving) electric charge that is caused by friction. Lighting in the sky is a result of static electricity!
I hope you enjoyed the experiment. Here are some printable instructions:
