Safe-Cracking Made Stupid Easy : Just Use a Magnet

SentrySafe puts all sorts of measures in place to protect your valuables and important documents. This particular SentrySafe has an electronic lock, four 1-inch bolts to keep the door firmly in place, pry-resistant hinges, and it's able to withstand drops of up to 15 feet. Tha ...more

Making Electromagnetic Weapons : Flashlamp Lasers

In my second article of the laser weapon series (see the first part here on CO2 lasers), I'll be expanding on the potential of pulsed lasers. I'm sure most everyone has seen those green and red laser pulses on Star Wars. Theoretically, those lasers could be built using a conc ...more

How To : Make a Tesla vortex

Take a journey to the center of a vortex. A beautiful whirlpool is created by the magnetic coupler inside a tall CD cover, driven by the Tesla CD Turbine on faucet water pressure. The Tesla CD Turbine is a little homemade turbine that thinks it can do anything. It's made from ...more

HowTo : Trigger Green Traffic Lights

Scenario: it's late at night, the roads are completely empty and you are stuck at the longest light ever. Solution: don't run a red- change it to green yourself. Avoid a ticket, save yourself some time (and perhaps a little gas). Many of you may have already seen Kipkay's ins ...more

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. The Tesla CD Turbine is a homemade turbine based on the ideas of Nikola Tesla and ...more

How To : Make a ball bearing rocket correctly

Place the neodymium magnets on the track and place four or five ball bearings in a line touching one side of the magnets. When you are ready to fire it, nudge the single ball bearing so it slowing rolls toward the magnets.

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. The CD Turbine is a homemade Tesla Turbine made from recycled CD's, CD cakebox, a nozzle and neodymium magnets. And glue. Lots of glue. This labour-saving devi ...more

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. The Magnetic Disc Pack inside t ...more

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. The Ble ...more

How To : Make a tightrope walking magnet

In this how to video, you will learn how to make a tight rope walking magnet. You will need a power supply with currents between 15 to 25 amps. A thick wire from a half to one centimeter is also needed for the tight rope. A small neodymium magnet will also be required. String ...more

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. This movie demonstrates the total over-use of technology in using the Tesla CD Turbine as a Decision Maker to help decide what to do during ...more
