Bring the charged ruler near one edge of the paper (but do not touch it). The paper will begin to spin towards the ruler. 4. Scientific Explanation (Why it works)
Use a balloon to lift small confetti paper off a table. Download Static Activity
When the plastic ruler is rubbed against the wool, electrons are transferred from the wool to the plastic, causing the ruler to become negatively charged (static charge). When this negatively charged object is brought near the electrically neutral paper, it repels the electrons on the surface of the paper, creating a positive charge on the side closest to the ruler. This phenomenon is known as . The electrostatic attraction between the negative ruler and the positive side of the paper creates a force sufficient to make the paper spin. 5.

Balance the center point of the paper on the tip of the pencil. Scientific Explanation (Why it works) Use a balloon
Cut tissue paper into butterfly shapes and make them "fly" off the table.
Add a for tracking how long the charge lasts based on different materials (plastic vs. vinyl). Add safety tips regarding static shock. Suggest a discussion guide for students. Let me know what you'd like to add! Six Activities with Static Electricity
Rub the plastic ruler or comb vigorously against the woolen item for 15–20 seconds. This creates a net negative charge.
