|PowerTRC Newtons Cradle Balance Balls 7 1/4 inch
Lowest new price: $16.95
List price: $16.95
This classic desktop display piece has become a must have for office decor.
Swing one steel marble back, let it go, and watch as kinetic energy causes the one on the opposite side to swing the same distance! If you're feeling saucy one day, try swinging two or three at once- just don't pass out from the excitement!
This desktop display model is a version of Newton's cradle, a device that demonstrates conservation of momentum and energy via a series of identically sized swinging spheres. When one ball on the end is lifted and released, the resulting force travels through the line and pushes the last ball upward. Because it uses Newton's Laws, it was named after Sir Isaac Newton, English physicist, mathematician and astronomer, but was actually invented in 1967 by an English actor.
- Classic desk toy
- Demonstrates Newton's Laws of Motion
- Frame and balls are made of metal
- Perfect gift for a geek!

1. Only use a little graphite dry lube quiet it down nicely if there is a little noisy. You can scratch off the graphite from the pencil with a knife.
2. Prohibit to add oil to lubricate. Because the oil will mix with dust in the air to be oil-dirt. That will make the friction to be even bigger. The stirling engine can't run freely then.
Stirling engine is traditionally classified as an external combustion engine. Please refer to wikipedia for more information about What is the stirling engine and How it works?

|Drinking Bird Perpetual Motion (2 Pack) The Original Vintage Retro Magic Sippy Dipping Bird A Science Wonder Wholesale Bulk Set of 2-The Incredible Bird That Drinks Water
Lowest new price: $12.95
Drinking Bird Perpetual Motion (2 Pack) The Original Vintage Retro Magic Sippy Dipping Bird A Science Wonder Wholesale Bulk Set of 2. This incredible scientific toy is a childhood favorite. Call it a game, Science experiment, educational, an office desk toy, call it what you like. This novelty is great for all ages. A great physics thermodynamic gadget and perpetual motion desk, school or office toy. Just dip the birds head into a glass of water and soak his head. Adjust the middle metal piece to sit just below the center of his body. Place a glass of water in front of him so when he dips down he will be able to wet his beak and head. The Thermodynamics should kick into action. It is really cool to see the Happy Bird in motion rocking, bobbing and dipping up and back to get his fill of drink. To operate the Dippy Bird, you get its head wet. As the water evaporates, fluid moves up into the head, causing the bird to become top-heavy and dip forward. Once the bird dips forward, fluid moves back into the abdomen, causing the bird to become bottom-heavy and tip up. Here is how a Dippy Bird works: When water evaporates from the fuzz on the Dippy Bird's head, the head is cooled. The temperature decrease in the head condenses the methylene chloride vapor, decreasing the vapor pressure in the head relative to the vapor pressure in the abdomen. The greater vapor pressure in the abdomen forces fluid up through the neck and into the head. As fluid enters the head, it makes the Dippy Bird top-heavy. The bird tips. Liquid travels to the head. The bottom of the tube is no longer submerged in liquid. Vapor bubbles travel through the tube and into the head. Liquid drains from the head, displaced by the bubbles. Fluid drains back into the abdomen, making the bird bottom-heavy. The bird tips back up. If the bird dips into a cup of water, the fuzzy material absorbs water again and the cycle starts over.
- 2 PACK-You get 2 Drinking Birds in every order. Great for schools, retailers, party favors and science fairs.
- SIZE-The magic sippy bird is approximately 8 inches in height. Fill a glass with water, dunk his head and watch the magic begin. Makes for a great bobbing bird desk toy.
- FASCINATING-This Original retro novelty toy is a great science marvel and very interesting to watch perpetual motion. Dunking his head and getting it wet is his favorite thing to do all day! Look for our Hand Boiler coming soon.

How to play:
Let the steel little guy stand on the steel cylinder base, and give it a gently push.
You can let the little guy stand on only place, but please try carefully and slowly, just avoid any drop and break. It's proving the scientific theory and mesmerizing you for hours. Fair warning: it's totally addictive!
It is not an item that never stops working. It moves and swing after you push, and finally it will stop due to the resistance of the air and friction if you know more about the law of energy conservation, you will not ask why.
HISTORY OF THE TOY:
Balancing toys were popular in the 19th century. Dating back to ancient China and India, where they were most often carved from soft wood, the western balancing toys were traditionally made from tin or metal. Illustrations of balancing toys can be found in educational literature from the 18th century. The physics governing the movement of such toys intrigued and amazed people. Balance toys came in various forms, and our particular shape is traditionally.
