A description of the Windlass mechanism in the human foot.

Nikola Tesla's valvular conduit is another one of his forgotten inventions. Invented in 1920 it has largely been overlooked. What is it? In simple terms it is a one-way valve. That in itself is not special. What makes it special is the fact it has NO moving parts. Think about that for a moment. How does a valvular conduit work? The design uses a particular shape. When the gas/fluid flows in one direction it changes direction slightly, in a zigzag way but is relatively unrestricted and does not find much resistance. However, when it flows in the other direction because of the design, the gas/fluid gets spilt into two. These flows then end up meeting almost head on. This causes some resistance. This is repeated numerous times, each time reducing in pressure/flow. This type of valve is never going to work as a seal for your wine bottle, it simply does not work that well at low pressures. However, when high pressures are used it comes into its own and the ratio between two directional flows gets higher and higher. Why did Tesla invent it? Tesla invented the valvular conduit around the time he was doing work with Tesla turbines. It seems to compliment his work with Tesla turbines rather than being a separate invention. Tesla turbines are primarily concerned with laminar flows (steady flows) and work better at higher pressures. Experiments show that the Tesla valve on the other hand works best with pulsed flow. In fact it becomes highly effective with high pressure pulsed flows. How to use it Amazingly a valvular conduit can be demonstrated just by blowing into it. Blow in one end and not much passes through. Blow in the other end and air passes through much easier: The higher the pressure the more of the restriction. How does the gas/fluid get stopped if there is nothing mechanical to get in the way? The answer is bizarrely simple. The gas/fluid itself becomes the physical restriction. When is most effective? At high pressures. For more information, see http://www.grand-illusions.com/acatalog/Tesla-Valve---Plastic-728.html

Slow motion ball: You need a thick liquid, preferably honey, a heavy ball, and a sphere shaped container. Place the heavy ball in the lower half of the sphere. Fill the lower half of the container with honey a little more than half. If you use too little or too much, it will affect the motion of the ball. 2. Water fire starter. Credit goes to The King of Random for this idea. Be sure to check out his channel. He has a huge selection of amazing how to experiments. https://www.youtube.com/user/01032010814 You need a plastic or glass container with a curved area. The Pom bottles work great. Fill the bottle with water. Fold 2 sheets of paper in half, twice. Print or scribble a black mark on one of the sheets. On a sunny day hold the bottle near the paper, focusing the light on the black area of the paper. Once it starts to smoke and a hole begins to form, wrap the other sheet of paper around the smoking piece. Wave the papers through the air to feed oxygen to the spark. Continue this until the paper catches on fire. 3. No-leak magic bag: Al you need is a zip baggy, pencils and water. Fill the bag almost to the top. Zip it shut, and start sticking pencils through the bag. Sometimes a few drops will leak out, but overall, this is a simple yet impressive trick 4. Liquid Stacking: You'll need a tall glass or bottle. Dish Soap, vegetable oil, dark corn syrup, rubbing alcohol, water and food coloring. First add the dark corn syrup, then dish soap, then add food coloring to the water and pour it in with the bottle tilted, then add the vegetable oil (bottle tilted), and finally add food coloring to the alcohol and pour it in with the bottle tilted. 5. Invisible Bottle: You need glycerin, a glass and a bottle that will fit in the glass. Fill both glass and bottle with glycerin and place the bottle in the glass. It looks like the bottle disappears. 6. Dancing Liquid: You need a powered speaker, a tone generator (can be found online), corn starch, water and plastic to protect the speaker. Pour 1/2 cup of corn starch in a bowl and 1/4 cup of water. Mix. Pour the liquid into the speaker and generate a 60hz tone. 7. Magic Water Barrier: You need 2 of the same glasses. Hot water, cold water, food coloring and a thin piece of plastic or cardboard. Pour the hot water in 1 glass, the cold in the other glass, add food coloring, then place the plastic on top of the hot water glass. Turn the glass upside down, place it on top of the cold water glass, then carefully remove the plastic. Hot water is less dense than cold water, so it "floats" on top of the cold water. 8. Leidenfrost effect: You need a pan, water and a stove. Turn the heat on high for about 4 minutes then add the water. This experiment can stain your pans. 9. Reverse Illusion: Add all sorts of images or words behind a glass, then watch as it reverses when you add water in the glass. 10. Reversing Liquid: You need 1 big glass, 1 smaller glass, 3 mixing glasses, corn syrup, pipettes, food coloring, and clips. First pour the corn syrup into the 2 bigger glasses. Place the smaller glass inside of the bigger glass. Attach the clips to prevent the smaller glass from moving side to side in the bigger glass. Pour a small amount of corn syrup into the 3 mixing glasses. Add food coloring and stir. Fill each pipette with a different color, then add the colored corn syrup to your big glass. Turn the smaller glass carefully and watch the colors mix. Turn it back and watch them unmix. Thanks for watching! Have fun!

This is a really fun project and when you first see the results, chances are your jaw will drop. The main thing to keep in mind for this project is that you need a camera that shoots 24 fps. The effect that you are seeing can't be seen with the naked eye. The effect only works through the camera. However, there is a version of the project you can do where the effect would be visible with the naked eye. For that project, you'd have to use a strobe light. For this project you'll need: A powered speaker Water source Soft rubber hose Tone generating software 24 fps camera Tape. Run the rubber hose down past the speaker so that the hose touches the speaker. Leave about 1 or 2 inches of the hose hanging past the bottom of the speaker. Secure the hose to the speaker with tape or whatever works best for you. The goal is to make sure the hose is touching the actual speaker so that when the speaker produces sound (vibrates) it will vibrate the hose. Set up your camera and switch it to 24 fps. The higher the shutter speed the better the results. But also keep in the mind that the higher your shutter speed, the more light you need. Run an audio cable from your computer to the speaker. Set your tone generating software to 24hz and hit play.Turn on the water. Now look through the camera and watch the magic begin. If you want the water to look like it's moving backward set the frequency to 23hz. If you want to look like it's moving forward in slow motion set it to 25hz. Have fun!

It's done differently depending on what type of flow you have. A pipe is calculated different than an airplane wing etc. Some fluid dynamicists would tell you that it's an exact science. I personally feel that it's a bit subjective. The most difficult parameter to nail down in my humble opinion is the characteristic length. It's pretty easy for pipes, you just measure the diameter... but wings, plates, vortices...get complicated quickly. You'll notice in the video I refrained from saying anything like "Flow is laminar when Reynolds number is less than XXX" or "Flow is turbulent when Reynolds number is more than XXX". There are different schools of thought on this. Typically the transition between laminar flow and turbulent flow occurs somewhere between 2100 and 4000 (Reynolds number is unitless).

However, in the case of axis 1, the kinetic energy is the highest possible for a given angular momentum, and in the case of axis 3, the kinetic energy is the lowest possible for a given angular momentum (which can be easily shown from conservation of energy and momentum equations, and is also fairly intuitive from the fact that kinetic energy is proportional to velocity squared, while momentum is proportional to velocity - so in the case of axis 1, the smaller masses will have to be spinning faster for a given momentum, and will thus have more energy, and vice versa for axis 3 where all the masses are spinning: the energy will be lowest). In fact, this is a strict inequality - if the energy is highest possible, there are no other possible combinations of momenta other than L2=L3=0, and vice versa for if the energy is the lowest possible. Because of this, in the case of axis 1 the energy is so high that there simply aren't any other possible combinations of angular momentum components L1, L2 and L3 - the object would have to lose energy in order to spin differently. And in the case of axis 3, the energy is so low that there likewise is no way for the object to be rotating other than purely around axis 3 - it would have to gain energy. However, there's no such constraint for axis 2, since the energy is somewhere in between the min and max possible. This, together with the centrifugal effects, means that the components of momentum DO change.
