Fire Tornado
A combustible material, ethanol, is lit and placed on a rotating platform. The platform is enclosed with a screen, which creates a vortex of air inside. The rotating air reacts with the flame to create a tornado made of fire.

By jumping on a platform connected to a seismograph, you can create your own earthquake. The greater force you apply to this platform, the larger the spike on the seismograph.
Methane is pumped through soapy water to create bubbles with methane in them. When grabbing a handful of bubbles, dipping your hand into the water as you grab them coats you hand with a protective layer of water. Then when you light the bubbles on fire, your hand is protected from the fire for a […]
If the pages of two phonebooks are stacked with one another connecting the two books, it becomes seemingly impossible to pull the books apart. The harder you try to pull the two books apart, the harder the stacked pages in the middle are squished together, increasing the normal force and thus the overall force of […]
A hand-made electric guitar demonstrates how magnetic pickups convert the vibrating guitar string into currents that can be amplified and modulated. The guitar has a variable amplifier and signal modulator built in and adjustable with dials. This then gets fed into a commercial amplifier as a normal electric guitar would.
Winding up the wheel gives it gravitational potential energy. Once let go, this energy is converted into kinetic energy or falling and rotation. Then it bounces back from the bottom and begins to climb again, losing its kinetic energy to potential energy until it reaches the top and starts the cycle all over.
How fast can your eyes see movement? With a simple strobe light and a cleverly decorated fan, we are able to see the effects that sudden bursts of light, at the right emission frequencies, can trick our brains into seeing stopped fan when it is actually not. Best of all, it’s an experiment you can […]
On one end of the cannon we have a tube with a near vacuum, while on the other side has compressed air. Both end our sealed with aluminium foil, but once the seal is broken, the rushing air and the lack of air resistance due to the near vacuum are able to accelerate the ping-pong […]
When one end of a chain of beads is pulled from a jar and allowed to fall, the rest of the chain rise up to an arch, leaping from the jar. This effect begins with a rotation produced from the initial upward pull resulting in a downward force on the opposite end of the the […]
Weaving popsicle sticks into a particular design creates a sort of wave explosion when released. This “explosion” results from the release of elastic energy stored during the weaving of the structure.
The hovercraft has an opening for a leafblower to fill the volume, made of tarp, underneath. As the air fills the tarp it begins to escape out of a hole cut in the center of the tarp. This creates a thin cushion of air between the hovercraft and ground, effectively hovering resistanceless above the ground.
Given a pool table in the shape of an ellipse with a single pocket placed at one of the ellipse’s foci, the cue ball will always go directly into the pocket, no matter the direction it is hit in, so long as it is hit from the other focus.
This involves two masses on two separate strings hanging from a thin rod. As each mass oscillates as a simple pendulum, they become coupled by vibrations of the rod, demonstrating physics concepts such as resonance and synchronization.
A guitar string is suspended over a hollow wooden box, and pulled taut by free-hanging weights. By increasing the weight on the end of the string, the tension is increased, and the pitch of the sound that the sonometer produces increases. By moving a bridge positioned on top of the string, the string’s effective length […]
We create plasma with grapes by first cutting them in half, with the skin joining them still intact. The skin joining the two halves heat up, vaporize and burst into flame creating a plasma.
When air is evacuated from the inside of the hemispheres, due to lack of pressure on the inside and the atmospheric pressure acting on the outside, this imbalance makes it almost impossible to take them apart once sealed.
This demonstration shows the process by which clouds form by rapidly reducing the pressure inside a bottle with alcohol vapor inside, as the pressure decreases the alcohol rapidly condenses to form a cloud.
By adding rubber bands around the watermelon, pressure is exerted on the watermelon causing it to implode.
We have a hand crank generator, wind turbine, and a solar panel to demonstrate the conversion to electrical power from the energy generated by each of these renewable sources! We have a cell phone charger, lamp which you can try to power with the hand crank generator. There are volt and amp meters connected to […]
The “floating” effect of this fountain is achieved by a transparent tube that holds the tap in place while also feeding the tap water pumped from below. The water goes up through the tube and comes out at the top, creating the illusion of a floating faucet.
