192 Years of Bicycle Evolution [Kranked 8 - Revolve] Victorian Flea Circuses: A Lost Art Form "QUANTUM SHOT" #549Link - by A. Abrams If you can make a flea cooperate with you, you're probably good at politics I have to say, this is probably the strangest subject we ever talked about on Dark Roasted Blend. However, it is such a rich showcase of miniature art and craftmanship, and the "wow" factor is there as well: A flea, with legs finer than a human hair, can pull up to 700 times its own weight! (art credit: Leah Palmer Preiss) "Big fleas have little fleas... Andy Clark sends us his latest project - he's been researching this topic for about four years now and regularly publishes new discoveries along with other flea news on the Flea Circus Research Library blog. "The idea to make a Victorian Flea Chariot came to me when I wondered if it's possible to use simple techniques available in the 1800s to make one today. The chariot is approx 10mm long by 7mm wide and made from brass; the wheels are 5mm in diameter. Making the chariot can be seen here, with video of a final product. ...

Magnet Man - Cool Experiments with Magnets Cool Experiments with Magnets This web site is devoted to magnetism and the cool experiments you can do with permanent magnets and electro-magnets. Some of the experiments are very basic - things you've done since third grade. Others are unique - perhaps you hadn't thought of doing some of these before, or had difficulty in trying to set them up. Lists of the materials needed for the demonstrations, directions on how to assemble them, instructions on how to show them, and notes on how they work are all here for you. Also shown are several cool magnetic toys you can buy. Have fun with hands-on experiments! Rick Hoadley(For other cool toys and puzzles, check this out!)

ASPIRE Simple & Comples Machines In an unknown time and an uncharted place, the ASPIRE crew has accepted the challenge to assist in the completion of a city being constructed of massive stones. They must work without the advantage of modern technology. They have agreed to rely primarily on the use of the six simple machines to accomplish their mission. Before getting to work, two crew members, Harry and Pic, have used available materials to fashion themselves a tetter-totter just to give them something to do for fun. This never seems fair. Drag the slider bars to move Harry and Pic until they have becomed balanced. Simple machines give us an advantage by changing the amount, speed, or direction of forces. Would you have a problem if the door knob came off in your hand before you unlatched the door? From day to day do you find yourself using any of the six simple machines: Wedge Lever Incline Plane Pulley Wheel Screw

Simple Machines: Facts (Science Trek: Idaho Public Television) Once upon a time a person needed to move something heavy. He or she picked up a long stick and stuck it under the edge of the heavy object and then pushed down on the other end of the stick. And the first simple machine was invented. Simple machines are just that. The simplest form of using one thing to accomplish something faster or better. A tool. There are 6 basic simple machines; the lever, the wheel and axle, the inclined plane, the wedge, the pulley, and the screw. But what is work? The Lever The lever is a long tool such as a pole or a rod put under an object to lift it. Levers are all around us. The Wheel & Axle The wheel has always been considered a major invention in the history of mankind.

The Inclined Plane The inclined plane is simply a ramp. The Wedge The Pulley The Screw Measuring Work
