Roll a Soda Can Using Static Electricity
If your are looking for a quick and easy science experiment that will mesmerize young scientists without the mess, then try rolling a soda can using static electricity. This kind of experiment is a great way to occupy the kids in a positive way while you are making dinner or when the kids are a bit restless or they claim that they are bored. This mess free and supervision free experiment can be enjoyed by all ages of science enthusiasts. Note that an empty soda can has some sharp spots at the mouth of the can, so use caution when necessary around very young children.
When you rub the balloon against your hair or against the wool sweater, invisible electrons with a negative charge build up on the surface of the balloon. This is called static electricity. The electrons have the power to pull very light objects that are positively charged toward them. In this case the soda can is positively charged and the balloon holds the negative charge on its surface.
