Pasta pot, two chairs and a broom, string, paint and paper. Art and Science should never be separated!
This is a fab STEM activity. Investigating pendulums and creating an artistic record of your experimenting at the same time.

Or younger ones may just swinging the pendulum with different amounts of force and in different ways to get different patterns.
