When training for the running segment of the triathlon, it's very important to warm up properly. Warming up before the actual run with stretching prepares the muscles for the actual exertion of effort, and minimizes the risk of injury that may occur. Here are some light stretches for the shoulders and hamstrings along with light movements
I like checking the ferry cam in order to try to minimize the wait up the hill. Nothing beats driving straight onto the ferry (except maybe being the last car on the ferry).
Hi everyone! I love the ideas what you showed us and the how to make does electric stuffs, but I had some ideas:
Nikola Tesla. He was the man behind some of the greatest inventions of all time, including radio and alternating current. But perhaps his most visually fascinating invention is the Tesla coil. While maintaining a low current, it can produce dangerous high frequencies and voltages that can well exceed 1,000,000 volts, discharging it in the form of electrical arcs very similar to lightning.
The Telegraph reports that a team of researchers lead by Dr. Sang-Woo Kim of the Institute of Nanotechnology at Sungkyunkwan University in Seoul have developed a method for converting the energy from sound into electricity. They've applied the research to the charging of mobile phones, and while you don't have to yell with all the emotion and fear exhibited above by Drew Barrymore in Scream, it sounds like the more energy the better. Dr. Sang-Woo Kim says:
If you already have your basic keyboard shortcuts under control—we're talking classics here, Control-C (copy for PC) or Command-C (copy for Mac)—it's time to load up your memory bank. There are endless shortcuts available (truly endless—since you can customize them yourself), but you don't need to memorize them all, only those you expect to use most. Below, two cheat sheets for upping your keyboard maneuvering status from "basic" to "intermediate" for both Mac and PC users.
Another example of outstanding resourcefulness and ingenuity in the medical community (see earlier this week: Blood Sucking Plunger Could Heal Millions).
Looking for a front-yard upgrade that'll have visitors beating a well-lit path to your door? The answer is an easy to install pathway lighting set. Too often, we're forced to choose between form and function. But when it comes to the route that leads to your front door, you can have it both ways: a pathway lighting system that combines the safety and security of good exterior illumination along with decorative elements that enhance your landscaping. Even though you might not have any experien...
The durability and aesthetic characteristics of brick patios and walkways make for the foundation of great spaces around your home. While installing brick walks and patios is not a difficult task, it may be rather time consuming depending on the size of the patio or walkway. When laying brick that will be walked on it is necessary to use paving quality bricks. These bricks are generally fired longer and at a higher temperature making them more suitable for a variety of weather conditions and ...
Are you sitting down as you read this? You might want to stand up for a little bit. In case you haven't heard, sitting for prolonged periods of time is really bad for your long-term health—so bad that chronic sitters are 54% more likely to die of a heart attack, even if they are non-smokers or regular exercisers.

With these tips, you can minimize the likelihood of avalanches and danger. Watch this how-to video, and you'll be able to ski safely in deep powder without fear. Ski safely in deep powder to avoid avalanches.
Redstone and electricity have much in common. They both have what's called resistance. That is, they only travel a certain distance before the signal degrades to the point where it's unusable, and they take a certain amount of time to get there. With electricity, that time is nearly instantaneous because electricity is extremely fast. Redstone, on the other hand, is pretty slow.
In this article, I'll show you how to make a portable prank stun-baton. Powered by static electricity, simply charge up the baton, and discharge it for a static surprise. The concept behind this device ties in with Leyden jars, and their tendencies to retain static electricity.
Contrary to popular belief, it is possible to cool down during the hot summer heat without blasting the A/C in your house and opening the refrigerator every few minutes to feel the cold, machine-made air blow against your overheated face.
Ok, I know nothing about this, but if this is true, does that mean we can toss out the millions of cables that are hiding in closets, garages and basements? According to the article, there's going to be HDBaseT, which can carry both video and audio signals, and a network connection, a USB connection and electricity with a single cable.
If you ever find yourself in the unfortunate predicament of being stranded outdoors in the snow, don't eat snow off the ground. Eating solid snow will sap your body of precious internal heat (since the heat will be used to melt the consumed ice), so it is best to melt the snow completely before drinking to stay hydrated.
Direct current (DC) by definition flows in one direction. Alternating current (AC), on the other hand, periodically changes direction, or reverses polarity. It is indeed possible for a portion of a circuit that is normally DC to periodically change direction, or reverse polarity like an AC circuit.
This low impact woodland home in Wales is the cream of the crop. The woodland home was built entirely of natural materials, and best of all - only took 4 months and $5000 to complete.
What do Jeff Foxworthy and Nikola Tesla have in common? Not much until this insane innovation came into existance.
Let's take a step back in time to the Mesozoic era of WonderHowTo. Before the time of electricity, your mother and I used to follow step-by-step tutorials on how to make a Lockheed Martin F16...from papyrus.
Time to prepare for that upcoming insufferable summer heat. For real. This tutorial actually works.
How to train a cat to use a toilet - really. I could not invent this stuff. When I first saw this video, I knew my life would never be quite the same. This ranks up there with the invention of electricity or the discovery or DNA. Now, I don't need to smell that litter. I don't have to change it. I don't have to buy it in the store anymore.
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 about this amazing inventor here), who used his Tesla coils to transfer wireless energy to light bulbs in demonstrations (photo below). However, the circuit described in this article consists of a flyback transformer, n...
In this series, I'll be exploring electromagnetic weapons, how to build them, their function and application to the future, and the amazing possibilities electromagnetism has to offer. First, the electromagnetic pulse generator, or EMP. You've probably heard of these before, and their devastating effects on electronics. A simple EMP consists of a capacitor, transformer, trigger, and coil of copper wire. This, when triggered, would produce an intense magnetic field for a brief period, similar ...
Unfortunately, toxic and belligerent people are not as avoidable as we would like for them to be. They show up in our work place, schools, neighborhoods—sometimes even within our own circle of friends and family members. The best we can do is minimize our interactions with them and plan for exit strategies to cut the conversation short. If an interaction is avoidable because the person is your boss or family member, then arm yourself with a few verbal defense moves to keep yourself from getti...
As some of you Mad Science readers will remember, we recently covered the separation of water into hydrogen and oxygen using electrolysis. Passing a current through water can rend it apart, but we can also recombine that oxygen and hydrogen to make electricity! This is the principle behind those vehicles run by hydrogen fuel cell engines.
Jet lag is inevitable when you're traveling long distances by plane, and it can leave you feeling completely wrecked for several days to a week after you arrive at your destination.
Whether you just got a brand new laptop or you've had an old notebook for several years, it's in your best interest to maximize your laptop battery life so you get the most out of your computer.
Infowars has a great new article on the myths of 'limited war'. It's a great read. Here are some excerpts:
In this article, I'll show you how to create a simple yet accurate demonstration of the "rising ionized gas" principle. In other words, a transformer, two metal prongs and lots of evil laughter. Remember those large "towers" in the background of Frankenstein movies with a "lightning bolt" rising upwards every few seconds? That's called a Jacob's Ladder; one of the coolest awe-inspiring demonstrations of high voltage. Here's a video of the final product: Materials and Tools
One of the creepiest musical instruments ever is undoubtedly the theremin, a device originating from the early 20s that emits eerie sounds with a just a wave of the hand. If you've seen the original movie The Day the Earth Stood Still, you know what I mean—freakishly creepy. Playing the theremin can be off-putting for some, since it's a relatively pricy gizmo, but a new geek gadget called the EaTheremin aims to make all of us professional, dinnertime theremists.
One of the best Flash games inspired by urban gardening. One simple way of alleviating food shortage or rather minimizing your food expenses: Planting your own food. Of course this won’t literally save you from a zombie apocalypse but this could surely save you some extra bucks.

Below, designer Chris Woebken's Flicflex isn't a new concept (Woebken displayed it at MOMA in '08), but still amazingly cool. And still not on the consumer market. Watch his paper thin, magazine-like "page turning": "Opening a letter, unfolding it and feeling the texture of the paper is a very tactile experience compared to receiving an e-mail. On top of the content itself, the behavior and micro-interactions adds a level of engagement to the medium. Flicflex explores the possibilities of fut...
Heed the NSFW. This is some mature content. So, IF you're at work on this fine Saturday morning, you may want to hover over "minimize"...
Originally discovered in dry lake beds in Tibet, borax is a mineral and a salt of boric acid, and is usually sold in white powder form in drugstores. Like baking soda, borax has many household cleaning uses, and can also be used to get rid of insects and pests from your living space.

If you want to avoid catching the cold this season, act like a complete germaphobic nut and wash your hands frequently. Wear gloves to avoid directly touching frequently-touched public surfaces that may carry germs, such as doorknobs and handrails.
A scale factor is a number used as a multiplier in dilation. Dilation is the act of being enlarged or minimized. Say you have a dimension of 3''. The scale factor is 2:1. So, you multiply the dimension by the scale factor to get your new dimension. After you multiply those numbers, you get 6''. Here is a link that relates to this subject. Scale Factor.
If you've had wooden furniture in your living space for a while, chances are that you've accumulated at least a couple of nicks and scratches on the surface. Before you spend money on a professional wood refinisher to restore the surface, try out some of the DIY techniques below using common household items to minimize the visibility of the scratch.
