25-inch Atwood machine with two 2-inch blue-plastic pulleys on an aluminum rod

Speed-controlled 6V motor driving two cams pumps four spring-mass systems at any chosen frequency

this demonstration electroscope detects and visually quantifies the magnitude of static charges

providing lightweight projectiles for collision-and-ramp experiments where steel or glass would carry too much momentum or break on impact
