The Happy Drinking Bird is So Popular, We've Made it Our (Un)Official Mascot

The infamous Drinking Bird has been a popular toy among children and adults for years. Once Drinking Bird's head is dunked in water, it will begin bobbing back and forth taking "drinks" with every bob.

Drinking Bird works using properties of thermodynamics, converting thermal energy into mechanical energy. The head and lower body of the bird are hollow glass chambers that are connected by a glass tube. The tube dips into the liquid (methylene chloride) in the lower body allowing the liquid to move up the tube when the temperature of the head is slightly cooler.


As the drinking bird tilts over, the liquid is eventually removed from the lower body and the lower portion of the tube. The vapor above the liquid then rushes up the tube which equalizes the pressure in the head and body. With this, the center of gravity returns to the lower body and with one swift motion, the bird swings back up away from the water.

Drinking Bird comes wearing a blue hat and red feet. The liquid comes in red or blue. Please let us select the color for you.

Radiometer
The Radiometer - A Real Solar Engine!
$11.95

The Radiometer provides an introduction to the study of thermodynamics that sits on your desk or table top. Set it in sunlight or incandescent light and watch the mill inside spin!

The radiometer consists of four vanes, each has one blackened side and one silvered side. It is encased in a clear glass bulb that has a near perfect vacuum. So what happens to make the radiometer "work"?

Crookes originally believed that sunlight falling on the light-mill turned the vanes so that the black surfaces were being pushed away by the light. He thought that this demonstrated that light radiation pressure on the black vanes was turning it round just like water in a water mill.

The problem with Crookes' explanation is that light falling on the black side should be absorbed, while light falling on the silver side of the vanes should be reflected. This means that there would be twice as much radiation pressure on the metal side as on the black and the mill would actually turn in the opposite way.

What really happens is that the faster molecules from the warmer side of each vane strike the edges obliquely and impart a higher force than the colder molecules. The movement of the vane as a result of tangential forces around the edges, is away from the warmer gas and towards the cooler gas with the gas passing round the edge in the opposite direction. Therefore, the movement is actually due to what happens near the edges of the vanes rather than at the faces.

Try it out yourself and watch thermodynamics in action! The radiometer's four vane rotor spins continuously up to 3,000 RPM. It is 5" high and 3" in diameter.

Static Electricity Bulb/Human - Powered Light
$4.95

CLICK HERE

Sure you‘ve seen static electricity at work: “static cling”, bad hair days, a shock from a door knob - but now you can put all of that “body electricity” to good use and light a small neon light bulb. Body static electricity can be in excess of 10,000 volts - but amperage is so low, it’s harmless!

Hold on to one of the light bulb wires and walk across your carpet, dragging your feet as you go.. This builds up a charge of static electricity that discharges through the light bulb in your hand. You power the bulb!

Try it in a darkened room to see the full glow. You need to generate static electricity (think enough to get a small shock when you touch something metal.) That is how the bulb works. If you generate a large enough charge, the bulb glows in free air. The winter is usually when your house is closed up and air has less humidity, so that is when the bulb is most effective. You can also place the un-held bulb wire next to the human-powered light bulb, BUT NOT TOUCHING a metal object like a lamp or TV. This allows the static electricity from the device to discharge from your body through the bulb.

Electricity has never been more fun!

Impossiball - The Ball With A Mind Of Its Own!
$4.95

CLICK HERE

Ever see a ball defy gravity?
Impossible?
Not with the Impossiball!


The Impossiball looks like a simple little rubber ball but let it out of its package and stand back - the Impossiball does crazy bounces and rolls, defies gravity and logic, will come to a complete stop on a hill, will let you bowl backwards, and lets you throw the zaniest wobble ball you've ever seen!


Dual density halves - one a sicko lime green, the other a wacky rainbow swirl, make the Impossiball always roll in a circle - you can set up some household objects like bowling pins, roll the Impossiball in the opposite direction from the objects, and the Impossiball will go in small or large circles and knock the objects down.

Pretty darn cool if we do say so ourselves...and we did.

Me too normajx2
Every kid should have the drinking bird

Yep, I dont know exactly how long those birds have been around but I know they were in the late 60's because I had one then
