Pressure
Nicole demonstrates atmospheric pressure keeping water in an upside down jar.
Jim pushes a large needle throuh air-filled balloons and not a one pops!
Nicole pushes a pencil through a water-filled baggie and not a drop is spilled!
Curt demonstrates atmospheric pressure crushing a can that has had hot steam quickly cooled.
Curt demonstrates atmospheric pressure pushing an egg inside a flask that has been heated then allowed to cool.

Pressure, Inertia and The Bed-of_Nails
Jim takes a sledge hammer to Leah who puts her trust in her knowledge of Physics.

Sound
Leah demonstrates how sound travels in a medium by putting a loud alarm in a vacuum jar.
MOVie
Angular Momentum
Conservation of angular momentum is demonstrated using a bycycle wheel and rotating chair.

Bernoulli
Nicole demonstrates Bernoulli's principle using a hair dryer and two ping pong balls. John explains Bernoulli's principle by (with the help of Nicole and Nick) spraying toilet paper out over the audience using a leaf blower.
MOVie
Pendulum
Jim and Robert Demonstrate energy principles using a pendulum.
MOVie
Inertia
Leah uses a broom to quickly knock a tray out from under 4 eggs resulting in the eggs falling into containers that were under the tray.

Jim does several demos on sound, including interference, beats and the doppler effect as is shown here.
MOVie
Resonace
Nicole shows how beatuiful musics can be made by cutting copper pipes to the right length.

Momentum
Jim rides the Rocket Cart. Notice the plume emitted from the fire extinguisher as he takes off. In the second picture...well...sometimes things don't go according to plan.
MOVie
Hovercraft
After the show the kids take turns getting rides on the hovercraft.

Waves
Kids get to observe the wave machine up close after the show.
