DIY Scientists Beware: When NOT to Use Household Chemicals for Your Projects

The only thing better than successfully pulling off a new experiment is doing it with household materials. You get to laugh in conceit as professional scientists everywhere spend all their grant money on the same project you just accomplished with some under-the-sink chemicals! However, there are times when DIY gets dangerous. Some household chemicals are not pure enough to use and some are just pure dangerous. Let's take a look at two problems I have encountered in the course of mad sciencing.

Red Wine: The Secret to Superconductivity

We've all heard of the power that red wine holds. It can help lower risks of heart disease, boost your brain power, and can even recharge your car battery. But last year, a group of Japanese physicists made headlines when they announced that they could induce superconductivity by soaking metals in red wine. But why red wine?

10th Time's the Charm: Success and Failures of Making a Jam Jar Jet Engine

I finally got around to trying out this jam jar jet project. The most successful and longest lasting pulse was somehow the only one I did not record. You can imagine how frustrating that probably was, though my tenth and final attempt was nearly as satisfying. But even the failures were fun to watch, especially the blue flame floating, almost dancing, around the jar. I especially liked the small foghorn sound that my first failed attempt produced.

Arduino Air Force: DIY Robotic Cardboard Quadcopters

You're hellbent on taking over the world, but one race of robotic minions isn't enough for you. With your hexapod robots acting as your ground forces, it's only natural to take to the skies. These cardboard quadcopters are the perfect air force for you. Combined, you are mere steps away from starting your evil takeover. Now you just need some water bots. The cardboard flying quadcopters are built around the MultiWii platform with the twin power of Processing and Arduino, so they are actually ...

News: This DIY Mini Tesla Coil Packs 380,000 Volts of Lightning

At one point in time, Tesla coils were actually used for things like wireless telegraphy and electrotherapy, but as technology advanced, they shifted to a slightly more enjoyable purpose—entertainment. What's even more entertaining than using a Tesla coil? Building your own. One of the best portable Tesla coils out there is this mini acrylic version by Daniel Eindhoven, aka TeslaCommander. It's made almost entirely of acrylic plastic, minus the steel sphere, and copper wire and tubing. When t...
