The Tesla CD Turbine is a little homemade turbine made from CD's, CD spindle, supermagnets, and glue. It runs on faucet water pressure.

How To: Reverse magnet rotation with a Tesla CD turbine

Balls go flying as MrfixitRick attempts to show how certain conditions cause a magnetic ball to reverse its direction, mysteriously revolving backwards to the rotating magnets of the CD Turbine.

How To: Reverse rotate magnetic balls with a Tesla CD turbine

Unusual magnetic phenomena observations are found here. First, we see a rotating and revolving ball magnet in a pyrex bowl. The revolving was expected; the rotating was not. Is this the same phenomenon as the Earth rotating around it's axis as it revolves around the Sun?

How To: Use magnetic balls with the Tesla CD turbine

The Tesla CD Turbine (the little turbine made from recycled CD's and magnets) is used as a magnetic test bed for this SinkScience experiment. Here, six 3/16 inch diameter neodymium ball magnets are placed in a plastic bowl above the CD Turbine.

How To: Make a vortex with the Tesla CD turbine

Use the Tesla CD Turbine running off tap water-pressure as an experimental testbed.

How To: Spin salad with a Tesla CD turbine

MrfixitRick demonstrates a magnetically-coupled Salad Spinner run by the Tesla CD Turbine on faucet water pressure.

How To: Light a flashlight up with a Tesla CD turbine

MrfixitRick demonstrates the Shake Flashlight Shaker, as it generates electric power out of faucet water pressure. A Tesla CD Turbine is used to convert the kinetic energy of water into rotation. Then, a connecting rod and magnets charges the built-in battery of the shake flashlight.

How To: Blend things with a Tesla CD turbine

The Tesla CD Turbine Blender Attachment is a SinkScience test of the new Kitchen Edition of the CD Turbine mated to a recycled blender from the Thrift Store. The CD Turbine, made with recycled CD's and neodymium magnets, is running only on faucet water-pressure power.

How To: Make hydro-electric power with a Tesla CD turbine

MrfixitRick shows how to make hydro-electric power using faucet water pressure, a Tesla CD Turbine, and a Subaru radiator fan motor.

How To: Spin things on a Tesla CD turbine

MrfixitRick and his assistant Rowan try four "Will It Spin?" experiments in an attempt to see if different objects spin with the rotating magnetic field of the Tesla CD Turbine.

How To: Run the Tesla CD turbine with simple CD disc pack

This is the first live action run of the Tesla CD Turbine II with simple hi-speed CD Disc Pack. This particular model of the CD Turbine has no magnets, as well as no shafts, no bearings, no seals and no blades.

How To: Use an in-sink Tesla CD turbine and magnetic coupler

This is a running demonstration of the water-pressure powered Tesla CD Turbine III and Magnetic Coupler, running smoothly and safely at up to 1000 rpm at the sink. The CD Turbine is made from recycled CD's and neodymium magnets.

How To: Align the telescopes finderscope with primary optics

See how to align the finderscope with the primary optics in this brief tutorial on your telescope. Watch this Amateur Astronomy for Beginners - Telescope Finderscopes.

How To: Use a planisphere and binoculars for stargazing

This video gives you some advice for beginning your hobby in amateur astronomy and how to use a planisphere and a pair of binoculars in this Amateur Astronomy for Beginners - Planisphere and Binoculars.

How To: Make an astronomical journal

Keep your stargazing sights and new experiences logged in a journal. Watch Amateur Astronomy for Beginners - The Astronomical Journal.

How To: Use red light to preserve night vision when stargazing

Here, you'll see the use of red light to preserve your night vision, in Amateur Astronomy for Beginners - Red Light. Bright lights could make it harder for you to see those stars, so use red light, because the rods in your eyes can take it better.

How To: Choose the right eyepiece for your telescope

Learn the basic information on eyepieces for your telescope, so you can gaze at the stars correctly in Amateur Astronomy for Beginners - Eyepieces. Learn the difference between low, medium, and high power eyepieces.

How To: Make a battery out of cans and water with Walter Lewin

The best physics lecturer, Walter Lewin, makes another wonderful physics demonstration after having read a lecture on batteries.

How To: Learn about advanced robotic plasma cutting technology

Here is an educational video for ART (Advanced Robotic Technology) Plasma customers. The HDP Plasma SX Profile Cutter is designed for heavy duty manufacturing environments where power, precision, speed, quality low cost, productivity, and durability are demanded by business owners. See in these sixteen videos how it works, from the inside out, and another video on what it actually is.

How To: Build your own microscope

Dr. Kiki explores the inner workings of microscopes while our Magic Creator, Moujan Z, remixes empty Altoid cans into a cool and useful container, Sarah makes you a a Muxtape, and Heather goes fencing - all on PopSiren!

How To: Collect meteorites

Astronomy editor David J. Eicher shares treasures from his personal meteorite collection and gives advice on starting your own.

How To: Go meteorite hunting on a dry lake bed

My name is Ruben Garcia and I'm a meteorite hunter. These videos are of a two day meteorite hunt. Just me and my video camera out in the wilderness!

How To: Etch an iron meteorite

Learn how to etch an iron meteorite to reveal its hidden crystalline structure. This guy is specifically etching a Campo Del Cielo meteorite. Why? So you can see how to do it yourself.

How To: Identify a meteorite from just a crummy rock

Here is a cool show that is all about meteorite identification! These two videos touch on some characteristics of stony (chondrite) meteorites that can help you to positively identify a meteorite.

How To: Read electrical resistor color codes

This video describes Resistor Color Codes and how to read them. It relates Resistor Color Codes to scientific numbers and engineering notation.

How To: Recognize different voltage sources for electricity

This is a recording of a class lecture on Voltage Sources. The first part describes how mechanical friction can generate voltages.

How To: Be aware of electricity and matter

In the first video, you'll see how contact between different materials can result in attraction or repulsion. Experimental results are discussed that led to Ben Franklin's one fluid theory of electricity. It explains how clues were found from rubbing different materials together.

How To: Use switches safely for your electrical needs

In the first video, it introduces the principles and terminology of mechanical electrical switches. It covers terms such as contacts, normally open, normally closed, poles, and throws.

How To: Use Ohm's Law for your electrical needs

The first video introduces the basic electrical quantities of charge, current, voltage, and resistance. The concept of quantities and units is explained. The units of Coulombs, Volts, Amperes, and Ohms are described. The three basic formulas of Ohm's Law (E=IR, I=E/R and R=E/I) are also introduced.
