Electrostatics Nicole and John rub balloons against fur and cover two audience members with the balloons. |
Diffraction John demonstrates diffraction using a gas discharge tube and diffrraction gratings handed out to the audience. |
Faraday Cage Justin demonstrates electrostatic sheilding using a screen and transistor radio. |
Magnetic Induction - flash bulb Jim surprises everyone by inducing current in a loop of wire as it passes through a strong magnet. The loop of wire is attached to a flash bulb and the light are turned down...flash! |

Helmholtz Coils Jim demonstrates two large Helmholtz coils. Current runs through wire loops made on a hula-hoop and the magnetic field produced deflects a compass needle. Jim also runs current through two suspended wires. The forces between the two wires is clearly visible. |
Internal Reflection. Ken demonstrates internal reflection by pointing a laser beam into a stream of water and and into a plexiglass spiral. |

Justin Demonstrates magnetic induction using jumping rings. A strong electromagnet induces current in a ring which opposes the magnetic field of the electromagnet. If you look carefully you can see that one of the images shows the ring in the air. |

Light Modulation Tim demonstrates light modulation using laser and stereo. A radio signal is controlling the intensity of the laser light, which is sent around the room and directed at a photo-cell, which in turn is amplified and sent to a speaker. |

Speakers & Laser Brad places a mirror on a speaker and reflects a laser beam off the mirror. |
Leyden Jar John & Nicole collect charge from the Van de Graaff to the Leyden Jar and show where the charge is located. |
Interferometry John demonstrates the motion sensitivity of a Michelson Interferometer. |

Chain Reaction With help from an audience member, Ken demonstrates a chain reaction using about 100 bouncing balls and about 50 mouse traps. |

Magnetic Damping John demonstrates magnetic damping using an aluminum plate and strong magnet. |
Rainbow Ken produces a rainbow using a prism. |
Scattering of Light Ken demonstrates light scattering and how it produces the colors in the sky. |
