Hair raising stuff with Saoirse!!
Static electricity
For this experiment you will need:
• an electric hair dryer with circular nozzle
• a balloon
First, blow up the balloon and tie off the end. Hold the balloon out at arm’s length and let go of it. Does it stay there, or drop?
Next, hold the balloon above your head at arm’s length, then blow hard at it as you let go. Can you keep the balloon in the air?
Now hold the hair dryer in one hand, turn it on, and point it up toward the ceiling. Place the balloon in the stream of moving air, and let go. Does the balloon fall to the ground or stay up? Why does this happen?
Experiment further with the hair dryer. If you tilt the nozzle slowly a little to one side, does the balloon stay in the air stream? Can you bring the nozzle back to vertical and make the balloon follow? How far can you tilt the nozzle before the balloon falls? What causes the balloon to stay in the stream of moving air?

Build a Circuit
A circuit is a path that electricity flows along. It starts at a power source, like a battery, and flows through a wire to a light bulb or other object and back to other side of the power source. You can build your own circuit and see how it works with this project!
