Five Demonstrations That Show Why Physics Is So Cool!
1. Shoot the target. Load, Aim, Fire!
Your students will ask you to repeat this demo over-and-over again. The suspense of waiting for the target-to-drop and for the gun-to-shoot will mesmerize your students. At the instant the projectile is shot from the launcher the target is dropped. The ball will consistently hit the bull’s-eye of the falling target as both objects accelerate downwards at the same rate.
2. Ballistic Cart Accessory. Warning: may cause cognitive dissonance
Your students may not believe their eyes, but hopefully they’ll believe the physics. The moving cart will reliably catch the vertically launched ball every time regardless of the cart’s speed. This accessory works with your dynamics track system and is a great demonstration to show the independence of x and y motion.

3. Standing Waves. Strobe lighting is not just for rock concerts.
Dim the lights and let the show begin. Just like at the rock concerts, strobe lighting highlights the object of interest. The strobe also slows down the motion of the vibrating string so that students can see the features of the standing wave in greater detail. The Frequency and light intensity can be precisely adjusted for superior results.

4. Magnetic Demonstration System. May the force be with you!
When raised and then released the swinging solid paddle stops instantly between the gap of the Variable Gap Magnet while the slotted panel sails straight through with no issue. Both paddles are made of aluminum, so why the difference? The answer …Magnetic Dampening! Diamagnetism and Paramagnetism, and Force on a Current Carrying Wire – are other great demonstrations of this comprehensive system.

5. Ring Launcher. 10, 9, 8, 7…. 1, All Systems GO!
The ‘launched’ ring may not make it to the moon, but it will fly an impressive 2 meters straight up. The projectile is propelled by the Lorentz Force that arises from the interaction between the alternating magnetic field of the coil and the current induced in the ring. The Ring Launcher is a classic demonstration that includes 5 rings of different metals and dimensions.
