Static Electricity Simulator
Rub the balloon on the sweater to build up a static charge, then test its attractive power!
🔊 Turn on sound for static crackles!
🖱️ Click & Drag the Balloon to rub it against the sweater.
The Science of Static Electricity
Everything around us is made of atoms, which contain positive protons (+) and negative electrons (-). Usually, objects have an equal number of both, making them electrically neutral.
- The Triboelectric Effect: When you rub two different materials together (like a rubber balloon and a wool sweater), friction causes the materials to exchange electrons. The balloon easily steals negative electrons from the sweater.
- Opposites Attract: Because the balloon now has extra electrons, it is negatively charged. The sweater lost electrons, so it is positively charged. They now pull towards each other!
- Polarization (The Wall): If you bring the negatively charged balloon near a neutral wall, it repels the electrons inside the wall, pushing them deeper inside. This leaves the surface of the wall slightly positive, allowing the balloon to stick to it!
- Attraction (The Paper Bits): Small, light objects like paper bits can easily be polarized and lifted against gravity by a strong static field.
