In his eternal quest to demystify the nuanced wonders of physics for his students at Gar-Field Senior High School, Bill Willis, 65, has conducted a number of experiments that educate as well as entertain.
Once, he built a hovercraft from a leaf blower and cushion so he could demonstrate Newton’s laws of motion. Another time, he lay on a bed of about 1,000 upright nails to show how weight distribution can affect pressure. And, on other occasions, he has swung a bowling ball hanging from the ceiling at his face to show how kinetic energy cannot surpass potential energy.
