When a balloon is rubbed against a sweater, static electricity is generated. When it is brought close to paper scraps or a stream of water, the paper scraps are attracted and the stream of water is deflected, visually demonstrating the presence of static electricity.
1. Balloon attracts paper scraps due to static electricity
When a balloon is rubbed against a sweater, static electricity is generated. When it is brought close to paper scraps or a stream of water, the paper scraps are attracted and the stream of water is deflected, visually demonstrating the presence of static electricity.
2. Blowing a balloon with a bottle
Put baking soda in the bottle, place a balloon filled with white vinegar over the bottle opening, and the white vinegar will fall into the bottle, generating gas and automatically inflating the balloon. This is an acid-base gas generation experiment.
3. A balloon that can't be pricked
The tape is attached to the surface of the balloon, and when a needle is pricked through the tape, the balloon will not burst. The tape restricts the rubber from stretching.
4. Hot air balloon launch experiment
Place a lit small candle under the paper cup, and secure a thin and light balloon at the top. The hot air will rise and lift the balloon.
5. Pushing a can across the air with a balloon
When a balloon charged by friction approaches a flat empty aluminum can, the electrostatic attraction pulls the can to roll.
