The Laden jar †hat I experimented with use static electricity. The jar made a shock that was an imbalance of electrons. A static charge was created when a rag was rubbed on a record, and the rag was rubbed over the Laden Jar and I heard a crackling .The crackling that I heard was the static electricity balancing out between the record and the Laden jar. †hen l put my thumb on the tinfoil and my index finger on the paper clip that got charged up by the record.
