What’s it about?
The rule for static electricity is that different (opposite) charges attracts, while the same (equal) charges repel one another. Static electricity can be demonstrated in many ways. This science project will detect and demonstrate the presence of the unseen static electricity field that emanates from a CRT TV’s picture tube:
Topics covered
Static electricity, Insulator, Friction

How does it work?
Unfortunately, this section is only available in the e-book version of the project.
This science experiment works because all objects have both ‘positively’ charged electrical particles called ‘protons’, as well as ‘negatively’ charged particles called ‘electrons’. Normally objects are in a neutral state and the protons and electrons cancel each other out. The balloon is given a strong negative electrical charge when coming in contact with the static field of the TV picture tube, pushing it away from the screen. If the other balloon is also slightly negatively charged, the two balloons will repel one another, if not they will attract one another.
