Nick has started a garden that includes pumpkins, peppers, tomatoes, strawberries, and other plants.
He also did an experiment where he placed four pieces of bread in separate plastic baggies. One piece was left untouched as the control; one was touched with dirty hands, one with washed hands, and one with hands that had used hand sanitizer. He observed them over time and noticed that more mold grew on the bread touched with dirty hands. Great experiment for the times.
Nick built a golf ball run and tested it several ways. Video is included.
