This speed-drawing tutorial demonstrates how to draw a futuristic soldier character with a flamethrower and a gas mask on your computer. It moves very quickly, but if you can't keep up you can reference the artist's step-by-step sketches where he breaks down the steps he takes in copious detail. The background is intentionally vague so that you can fill in whatever you like, most likely a post-apocalyptic setting of some kind. A good view for any comic book, fantasy, or science fiction artist.
Want to make a simple electric motor at home? Andy and Mike show you how in just a few easy steps, using a block of wood, two paperclips, a AA battery, some insulated copper wire, and a magnet. This is a fun and simple science experiment that anyone can do at home. Wrap the wire seven times into a circular coil, with the enamel stripped off at both ends. Place the battery between the two paperclips, which serve as conductors and also hold the coil in place. Place the magnet below and between ...

This video shows us a fun science project to do with our kids; it teaches us how to make flubber out of glue and cornstarch. In one container pour a small amount of liquid starch. You can find this in most laundry aisles in the store. Next in another container, pour in an equal amount of white school glue. Mix the two together by pouring the liquid starch into the glue. If the mix is real sticky, add more starch and if it is real runny, add more glue. To color your flubber you can dab it over...

Fiber is a very important part of a diet and most people are not getting enough. It's recommended that you consume a minimum of 25 grams of fiber per day if you're a female and about 30 to 38 if you're a male. Learn what to eat for a high fiber diet in this nutrition how-to video.
Unfortunately, no one seems to have, or willing to share, the science of making a real teleportation chamber. That doesn't mean you can't make a prop one though. Parker put together this video to show us how. You will need foam core poster board, a hot glue gun, duct tape, a pane of glass or plastic, silver spray paint, black paint, and cardboard. Watch this video prop-making tutorial and learn how to build a teleportation chamber.
Objects become charged when rubbed against one another. This happens because negatively charged electrons flow from one object to the other.
Cake decorating is both an art and a science. Watch this four-part video to learn how to make Calla Lillies in gumpaste for your cake.
Let's face it: Powerpoint presentations are boring. For the most part, you use them as a lecture aid for science class or to give a presentation at work about market trends. Okay, we're making ourselves tired already. Point is, there's really not much going on with Powerpoint presentations, so make your next one as painless as possible by adding some cute animated clips.
We all know what elephant toothpaste is, but what's the best way to make this massive growing foam? Dr. Lithium from NurdRage has answers. He'll show you the best way to reproduce this chemical reaction to get the best foaming action! This is a classic science class demonstration.
In a previous Nurd Rage video (here), Dr. Lithium showed you that pyrolytic graphite was diamagnetic, and that it could be stably levitated over magnets. It was repelled by a magnetic field, and this repulsion was strong enough to levitate it. In this science video tutorial, you'll learn how to levitate plain old pencil lead this time.
If you prefer glow sticks over candles during a power outage, then this how-to is for you! Although glow sticks are used as temporary light sources, there are other applications for them. Divers use them for night diving, fisherman use them to catch swordfish, and the military uses them for light markers, along with infrared versions used in conjunction with night vision devices. But with all these handy uses for glow sticks, the most popular is — recreational use, like dancing at raves, some...
Rust protection doesn't have to cost a fortune. With a little zinc and some electricity, you can protect your precious metals from rust by galvanization. When you galvanize something, you're giving it a protective coating, and in this case, it's a zinc coating.
If you want to know the best way to get an accurate pH measurement, this shows the lab equipment needed and the processes used. When doing chemical reactions, sometimes the acidity or the basicity is important. This is usually defined as pH and measuring it can be very useful for getting the reaction right. There are a few ways to measure pH, and the simplest, cheapest, most reliable method is paper. But that's not all. See a whole lot of ways in this two-part video.
Various electrochemical reactions requires that anodes do not degrade when used. Carbon is cheap, but degrades easily and platinum is extremely expensive. In a previous video, you learned "How to make cobalt and manganese nitrates", and you saw that titanium could be used as a cathode, but not as an anode due to an effect called passivation.
In order to make manganese dioxide electrodes, you're going to need cobalt nitrate and manganese nitrate to do it. Making cobalt nitrate is fairly easy, but making the manganese nitrate is a little more complicated. But not impossible.
What is MnSO4 and MNO2, anyway? They are they molecular formula for Manganese Sulfate and Manganese Dioxide. And you can make one from the other. But how?
