Ralph Waldo Emerson once observed that "the seed of science" was "wonder," and taking a look at this nine-layer liquid tower from Steve Spangler's Sick Science! channel, one can't help but do just that — wonder. How is this possible? Is this magic or what? While it's not exac ...more

A hacker with privileged access to a Windows 10 computer can configure it to act as a web proxy, which allows the attacker to target devices and services on the network through the compromised computer. The probes and attacks appear to originate from the Windows 10 computer, m ...more

A lot of my hacks use salvaged parts from an old microwave, with the microwave oven transformer (MOT) being the most useful component. In this "Quick Clip," I'll be using a MOT again (a dual MOT stack) to make deadly flame-looking electricity jumping around midair. This scien ...more

In this article, I'll show you how to built a Wireless Transfer of Energy Transmitter. Simply put, this device will send electricity to a florescent light bulb and light it up, from up to three feet. The idea originally (at least, prominently) came from Nikola Tesla (read more ...more

Significant strides have been in the race to find antibiotics to treat superbug infections — those caused by bacteria resistant to the antibiotics used to treat them. Now, an international team of scientists has discovered a new antibiotic produced by a microbe found in Italia ...more

This is the third part of my electromagnetic pulse series (see Part One and Part Two). By now, I've covered the hardware and general concept of electromagnetic pulse generators, but how exactly do they disable electronics? How can an invisible field of energy have such a catas ...more

Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigato ...more

There are all kinds of theories—many supported by science—about what causes Alzheimer's disease. Tangles of protein called ß-amyloid (pronounced beta amyloid) plaques are prominently on the list of possible causes or, at least, contributors. An emerging theory of the disease s ...more

As researchers learn more and more about our intestinal bacteria—also called the gut microbiome—we're finding out that these microbes aren't just influencing our health and wellness, they're a useful tool for improving it, too. The bacteria in our intestinal tract must proper ...more

I'm starting to wonder if the people at Boston Dynamics have ever watched a Terminator movie. Not just because the robotics company with the oxymoronic name develops machines that are able to move around environments with animal- and human-like agility, but because the people ...more

It’s called Urophagia—the art of consuming urine. There could be any number of reasons for having the desire to drink your own urine (or somebody else’s). There’s the so-called term “urine therapy,” which uses human urine as an alternative medicine. In urine therapy, or uropat ...more

This article is a guide for making Chainmail Armor from start (simple wire) to finish (a finished chainmail shirt). We will be using the European 4 in 1 weave, as this is the most common weave. This is the weave that you usually see in movies. There are several sections to thi ...more

I finally got around to trying out another one of Will's mad science experiments and found out that this one was actually more satisfying (and less frustrating) than my slightly uncooperative jar jet. There's something very pleasing about making potassium nitrate at home in th ...more
