How To: Make an RC plane

In just under 4 hours, leftover parts were used to make a neat RC airplane called "The Junkyard Dog". Using mostly COX airplane parts from models gone by the wayside, you can make one with no plans or a kit.

How To: Make plasma with a light bulb

Make plasma with a light bulb. All you need is a microwave.

How To: Get liquid to rise into a glass with a candle

You take some water in a pan and a couple of candles. Light the candles then put something over it. Example - a mason Jar. In this experiment we used a beaker. Put the jar over the flames. The jar will cause the flames to extinguish and then the water will rise into the beaker.

How To: Float eggs on salt water versus fresh water

Derek's 5th Grade Science Experiment. Will eggs float better on salt water or regular fresh water.

How To: Make your own lava lamp

In this simple kitchen science experiment, you'll see how to make your very own, cool, lava lamp.

How To: Draw an arc with a Tesla coil

Have you ever wanted to use a Tesla coil to draw a fixed arc on a two liter plastic soda bottle? Who hasn't? Well, see how to do it, right here!

How To: Make hot ice

How to make "hot ice" out of saturated sodium acetate solution.

How To: Make a salt crystal garden

This is a timelapse of a salt crystal garden growing on a toilet paper roll. You need salt, water, food coloring, ammonia and a dish with a pourous stiff object.

How To: Make holiday decisions with the Tesla CD turbine

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
