8B30.50 - Supernova Core Bounce

Code Number:
8B30.50
Demo Title:
Supernova Core Bounce
Condition:
Excellent
Principle:
Magnetic Field Coupling
Area of Study:
Stellar Astronomy

Disclaimer

Equipment:
Velocity Amplifier, Astro-BlasterTM Apparatus, WD-40, Safety Glases.
Procedure:

Lift the desired number of circular plates to the height you want and let them drop.  The small plate should jump to a height that is based on that combination.  You should almost reach the ceiling in LR1 or LR2 if you use maximum settings.

Lube the stem of the Astro-BlasterTM with some WD-40.  When dropping try and make sure that when it hits the ground the stem is pointed straight up.

NOTE: Safety glasses should be worn to protect the eyes of the dropper.
