Convection John & Brad demonstrate convection by heating up the air inside a balloon made of tissue paper. |
Convection Art demonstrates convection currents by placing hot red and cold blue water in an aquarium. |
Pressure Anura & Jim use atmospheric pressure to crush a large 50 gal durm. |
MOVie
Pressure Jim & Anura demonstrate how the pressure of many nails results is each nail exerting so little force that person can lay on the nails and have a concrete block crushed above them. |
PRESSURE John first uses atmospheric pressure to crush a 1 gallon can then uses liquid nitrogen to uncruch the can can. |
Jim plays the garden trumpet demonstrating show air moves when sound is formed. |
|
MOVie
Resonance Anura demonstrates resonance by balancing a candle and lighting both ends. The candles oscillate and the oscillations are sustained and wax alternatly melts on each end. |
Resonace John swings several loops of a chain making one loop swing while the others remains still as long has he moves his hands back and forth at the rate appropriate for the loop he wants to swing. John puts a slinky against a guitar and the sounds a slinky makes are greatly amplified. |
Carbon Dioxide - CO2 Tim and John blow up a balloon by placing CO2 inside. Tim and John place CO2 in water and watch the vapors pour out. |
Pressure Jim pumps up a PVC pipe which has confetti inside. When the cork pops, out comes the confetti. |
|
MOVie
Inertia Tim knocks a pan out from underneath 4 cardboard rolls supporting 4 eggs using a broom handle. After the pan is knocked out the eggs fall straight down into beakers supporting the pan. |
Pressure Art uses atmospheric pressure to push a hardboiled egg into a flask. |
MOVie
Brad demonstrates sound resonance inside a long tube by observing the height of gas flames when a speaker connected to a signal oscillator excites the air inside the tube. |
Tim shows how the air inside a flask changes density when heated and cooled by observing a balloon placed over the flask. When heated the air inside will inflate the balloon. When cooled the atsmopheric pressure will puch the balloon inside the flask. |
John and Justin give Art a ride on the hovercraft. |
Anura's son, Seth, lifts his father with a large lever. |
MOVie
Art with the help from someone in the audience demonstrates inertia by balancing a pen on a hoop over a bottle. The hoop can be removed quickly so that the pen falls into the bottle. |
Charlie, a member of the audience, is asked to separate the halves of a sphere that has been evacuated. He is pulling against about 200 pounds of force produced by the pressure of the atmosphere. |
|
MOVie
Justin stands in front of a large pendulum putting his trust in the laws of conservation of energy. |
Tim does several demos with liquid nitrogen. Cool! |
Brad takes off across the room using a fire extinguisher and a tricycle and Newton's laws. |
A young audience member shows that with a little physics he can push around two full sized professors. |
John demonstrates just how off balance he can be. |
