Cellophane tape is allway sticky. But in this experiment, it seems to behave odd. In this experiment, we will understand more about the effect of static electricity.
Things Required:
Cellophane tape
Directions:
Press two pieces of tape onto a table, leaving a small piece hanging over the edge. Hold the ends of the tape and quickly pull both pieces off the table. Bring the two pieces near each other, but not touching.
This Is What Happens:
The pieces of tape move away from each other.
Science Behind It:
All materials are made up of atoms, which have positive and negative parts. When there is a gain or loss of charges, the object is said to have static electricity. Pulling the tape pieces from the table causes them to pick up electrons from the atoms in the table. Both pieces of tape are negatively charged. Materials with like charges repel (push away from) each other.
