In this experiment we will take a regular balloon and make it sticks to the ceiling - in a way that looks like it is a light helium balloon which is lighter than the air.
- Balloon - The balloon should be used as blown as possible - almost to the limit of its capacity.
- Hair :-) - To rub the balloon in it. You can also use a wool sweater.
Note: It is advisable to apply the experiment in a closed room. Because a light breeze that may pass through the window or the door can easily make the balloon fall.
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy.
A static electric charge can be created whenever two surfaces contact and separate, and at least one of the surfaces has a high resistance to electric current (and is therefore an electrical insulator). The effects of static electricity are familiar to most people because people can feel, hear, and even see the spark as the excess charge is neutralized when brought close to a large electrical conductor (for example, a path to ground), or a region with an excess charge of the opposite polarity (positive or negative). The familiar phenomenon of a static shock – more specifically, an electrostatic discharge – is caused by the neutralization of charge.
