Static Hair With Balloons Has A Secret
If you have a head full of hair, chances are, you’ve rubbed your head with a balloon at one point to get a static charge. It’s so common, that most of us barely think about what causes it. Scientists have tried studying the phenomenon and were unable to come up with a clear and concise reason as to why it happens. Previously, scientists claimed that electrons move from the atoms and molecules on your hair to the balloon. When the balloon has a negative charge, your hair turns to a positive charge, thus standing on end. This is called static electricity, though scientists later learned this theory doesn’t hold. It doesn’t explain why objects of the same material also build up a static charge. In an experiment with tiny grains of material, scientists, could not explain the static build-up and assumed that it may come from the water molecules that coat the grains. Still, it remains a complete mystery (Gizmodo).
