If you're a medical student, you'll learn a lot from this video lesson on examining your patient's eyes. If the patient is having trouble seeing, like double vision, blurred vision, pain or any other problem, a proper eye examination is detrimental to properly diagnosing and treating him/her. You can also determine and potential problems which may arise bases on your family history. Watch to see the complete procedure outlined, which is great for any med student or doctor. Even nurses can ben...
As a doctor, sometimes it will be necessary to perform a neurological examination of your patient to rule out any neurological disorders. Your objective is to identify abnormalities in the nervous system, to differentiate peripheral from central nervous system lesions, and to establish internal consistency. This is a great video less that outlines the complete neurological exam procedure. It's great for medical students or doctors, and even nursing students can learn a thing or two.

This presentation entitled: Pollinate Chain Reaction was produced by Mike Goedecke and Kane Roberts at Belief Design. There are many tips contained within on how to maximize your creative potential. Great to help inspire anyone in a creative field.
It's that time a year when winter storms begin causing havoc across the United States, and when "rotating outages" are common to help sustain the electrical grid during intense cold periods. That means pretty much anybody with snow and ice in their backyard can succumb to power outages. And no electricity means no electric heat.
Mechanical locks have been around since ancient Egypt, with the oldest known artifact found in the ruins of Nineveh, an ancient city in Assyria, Mesopotamia, which is just across the Tigris River from what is now Mosul, Iraq.
If your vehicle does nothing (doesn't crank over) when you turn the key in the ignition, then you might need a new starter. In this video, Scotty shows you how to check your starter and how to replace it if it's bad. Your first reaction for a non-starting car may be to jump start it, due to a dead battery, but if your battery is brand new, or if jump starting doesn't work, you'll need to get a starter tester to check out the starter. If it's bad— replace it with a new one! See how!
Watch this science video tutorial from Nurd Rage on how to make a test tube thunderstorm. They show you how to make the thunderstorm in a test tube using alcohol, sulfuric acid and potassium permanganate.
To get the Guerilla Tactics achievement / trophy in Bulletstorm, you must execute 25 skillshots in a single Echoes map. Skillshots are the most fun part Bulletstorm. This video will give you a handy step-by-step guide to getting the achievement in Collapsed Building.
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...
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.
Andy Field shows us a trick that has little set up and carries a high reaction. This trick is called the wrong prediction trick. You will need a deck of playing cards a wallet and a black magic marker. Take out the queen of hearts and write "9 of clubs" on the back of it. Stick the card in the wallet face side up this will be called the "force card". Find the 9 of clubs in the deck and slightly bend it to give a slight concave effect. Do the same to the queen of hearts. Fan out the deck face ...
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?
Hot ice is a very cool experiment. This is a recipe for homemade 'hot ice' that mimicks the sodium acetate one but only requires simple ingredients!
This video speaks to everyone who has ever bought anything online, or in fact, anyone who has ever bought anything period. How do you know what you're getting is genuine? Is it a fake product? Is it stolen goods? Is it impure?
It's a stormy winter night, and you're electricity goes out. You could grab some candles to add a little light to your life, or you could use glow-in-the-dark chemicals for a cool luminescent.

Watch this science video tutorial from Nurd Rage on how to test if a fertilizer has nitrates rather than urea or ammonia as its nitrogen source.
One of the most famous and repeated chemistry experiments involves money. Some would say this is more of a trick than an experiment, but you can be the judge of that. No one can just turn pennies into silver or gold coins, but someone with a few chemicals can. So, if you want to cooler cents in your pocket, try out this chemistry trick yourself. Nurd Rage (Dr. Lithium) shows you how to turn pennies into silver and gold coins using zinc.

Pour water into a cast iron bomb. Then bathe the bomb in a dry ice acetone slush. This will cause the reaction. This is to illustrate that the volume of ice is greater than of an equal mass of liquid water.
In this video, we learn how to easily balance a chemical equation. In a balanced equation, there should be the same number of atoms on both sides of it. There are no rules that explain how you get a balanced reaction from expression. First, start on the molecule or compound that is the most atomically complex. After you look at this, you can learn how to make the rest of the equation equal to each side. This is a complex process that you must walk through to figure out, but it will result in ...
Aqua regia (königswasser in German) is a very corrosive liquid made from a mixture of nitric acid and hydrochloric acid (1:2 - 1:3). This chemical mixture is so corrosive that it can even dissolve gold, and that's what you'll learn about in this video.
Olivia and Andrea created a song to the tune of "I'll stand by you" by the Pretenders to teach you how to balance chemical equations. A chemical equation requires coefficients in order to be balanced. You can balance a chemical equation by making use of the Periodic table. The example reaction in the song is that of aluminum and oxygen to produce aluminum oxide (Al + 02 -> Al203). You can systematically add coefficients to the reactants and products to balance the equation. A chemical equatio...
