Electrical Goo Electricity Science Experiment
Creating electrical goo is an easy science experiment to try if you are looking for a fun way to explore static electricity.
- Vegetable oil
- 1/4 cup measuring cup
- Mix ¼ cup of cornstarch with ¼ cup vegetable oil.
- Blow up the balloon and rub it against your hair until it is electrically charged.
- Now take a spoonful of the gooey mixture and hold it near the balloon.
- The goo should reach out toward the balloon and may even leap from the spoon onto the balloon.
How it Works:
The balloon becomes negatively charged when rubbed against your hair. The cornstarch is positively charged. Since negative charges attract positive charges, the positively charged cornstarch is drawn toward the negatively charged balloon. The vegetable oil helps restrict the movement of the cornstarch and thus creates the goo effect. Without the vegetable oil, the cornstarch powder would attract and attach to the balloon.
Make This A Science Project:
Test to see if the electrical goo behaves differently at different temperatures by cooling it in the refrigerator. Substitute cornstarch for other items like baking soda or flour to see if there are any observable differences. Use different items like plastic utensils, a plastic comb, a piece of PVC pipe, or a Styrofoam cup to try and create the negative electrical charge.
