The experiments with static electricity are among the easiest thing to do with children. A woolen cloth or your own hair can be used to carry a balloon, a PVC tube, or some disposable plastic plates. We also have experiments that explain magnetism and other activities to bring children closer to learning science.
1. Magic bubbles
Turn your children into magicians thanks to static electricity . In this experiment we teach you how to make soap bubbles move from one side to the other without touching them.
- Pot with liquid to make bubbles
- Plastic surface
- PVC pipe
- Hot glue
- Use the foam rubber to create a star to decorate the PVC pipe and turn it into a wand.
- Pour some bubbler liquid onto a plastic surface and spread.
- With the help of a straw, make one or more soap bubbles.
- Rub your PVC wand with a cotton cloth.
- Bring the wand closer to the bubbles. They will magically dance in the sun of your movements.
By rubbing the wand we charge it with static electricity . When you bring it close to the bubbles, they are also loaded and attracted by the PVC.
2. Separate the salt from the pepper
What happens when we spill salt and pepper together ? The grains get mixed up and it seems impossible to separate them. With this experiment with static electricity we are going to show you that it can be done.
- Fine salt
- Ground pepper
- Plastic spoon
- Dish towel
- Black paper or cardstock
- Add salt and pepper to the black paper.
- Rub the plastic spoon with a woolen garment or with your hair. This will charge you with static electricity.
- Bring the spoon closer to the pile. You will see how the peppercorns stick to the spoon.
The pepper is lighter so it jumps faster, attracted by the static electricity of the spoon and is gripped with greater intensity than salt.

3. Flying balls
Impress your kids with these experiments with static electricity with which you will make some balls of aluminum foil fly.
- Plastic plates
- Cotton rag
- Make some balls with the aluminum foil. Leave them on one of the plates.
- Take the other and rub it with the cotton cloth.
- Bring the one charged to the aluminum balls and they will start to fly attracted to it.
The plate that we have rubbed and the balls have different charges which makes them attract each other.
4. Magic bulb
Your children will not be able to believe that a light bulb shines in your hand without being connected to any socket. All you need is a balloon with static electricity to light it.
- Low consumption fluorescent light bulb
- Wool garment
- Go into a dark room and wait a moment for the children’s eyes to get used to the lack of light.
- Rub the inflated balloon against a woolen garment.
- Take the balloon by the mouthpiece and bring it closer to the hand in which you are holding the bulb.
- Move the balloon quickly back and forth but without actually touching the bulb.
- You will see how it lights up.
Static electricity from the balloon is what makes the bulb turn on. It is important that the balloon is well charged so you have to rub it vigorously for at least a minute.
If you have been interested in these experiments with static electricity, be sure to read the proposals we have to explain magnetism or the ideas that we propose to bring children closer to learning STEAM.
