                      PHESTIVAL of PHYSICS   

On Sunday, April 14, 2002 at 4:00 PM the PHYSICS CLUB at 
Lock Haven University will be holding a physics demonstration show 
in Ulmer Planetarium.  The show will include demonstrations on 
electricity, magnetism and optics.  There will be colorful lights, 
sparks and arcs.  It promises to be an enlightning and electrifying
event.  It should be fun for kids of all ages! The show is free and 
open to the public.

NAME			PRESENTER	NOTES
Van de Graaff  		Anura, Leah	hair standing up: darkened room and backlit her with
					spotlight - worked well

candle and mirror		Kyle		lit candle in front of parabolic mirror, candle appears to burn
					at both ends.  Need to rotate mirror so all can see effect
LED show			Jim		Red and green LEDs connected to an AC source and spun
					in circle.  When not being spun one can see a mix of colors.
					When being spun one can see how the red and green are 
					goind on an off.  One can even see gaps where the voltage is 
					below threshold for the LEDs.

eye rentention		 JohnJustin 		Wave stick in front of slide projector.  Eye retentions allows 
					one to see a complete imgage.
3D red/blue shadows 		Justin/John 		Two projectors with red and blue filters in front casting two
					shadows from person between projector and screen. Audience
					wears red/blue glasses and sees a "3D" shadow.
soap bubbles & show trubulence	Shelly/Kyle 	Flowing soap film.  Projector light passing through 1cm aperature
					allows one to project images of fluid flow on screen.
polarization of water		Justin/John		Use projection system as above to show deflection of stream 
					of water due to charged comb.
E fields			Jim		Wimhurst charges probes in oil on OHP.  Particles align with fields. 
Whimhurst			Jim		Leyden jar
Lenz's Law 		 Jim/Justin		drop magnet and non-magnet through copper tube.  Induced eddy
					currentsl slow magnet.
Lissajous figures		John		Two mirrors on two soda cans held in place with rubber band such
					that they oscillates when flicked.  Laser light produces Lissajous figs.
diffraction			Jim		diffraction gratings and laser light
refraction through water	Justin/John 		Laser lights heading in same direction to screen. One passes through
					water (aquarium) the other does not.  As angle changes one
					can see the spots on screen at different locations.
dances with mirrors		John		Put one leg in front of mirror the other behind.  Move one leg and
					reflection makes it look like both legs are seen.
