How To: Unclog a drain without toxic chemicals

Don't call a pricey plumber! Anyone with a few tools can unclog a drain -- without even resorting to those strong, toxic chemicals. Most of the time, anyway. You will need baking soda, vinegar, rubber gloves, cleaning rags or duct tape, a rubber plunger, a plumber's snake, petroleum jelly, a bucket or pan, and a length of hose. WARNING: Do not try this if you have already used a commercial drain opener, as it can create harmful fumes.

How To: Kill Cockroaches in a Green Way

Cockroaches are one of the most durable and and irritating forms of life on Earth. Many turn to toxic chemicals to get rid of them, but that's not very green is it? This video will give you some eco-friendly tips for preventing infestations, trapping insects, and disposing of them once you've caught them. Yes, cockroaches are part of nature. No, that doesn't mean we're not going to kill them.

How To: Do waterless lithography

This video walks you through the steps of how to do waterless lithography. Waterless lithography is a lithographic process that does not require heavy or expensive presses or too many toxic chemicals. It is based in the idea that water and silicone don't mix.

How To: Use gravimetric analysis to analyze sulfuric acid

This video is based on a chemistry experiment. This video is going to explain to us how to use gravimetric analysis in order to analyze sulfuric acid. This experiment should not be done for those who do not have a fundamental knowledge of chemical compounds, reactions and chemical safety. He explains first what he is about to do before he does it. Sulfuric acid is acidic and can be toxic if ingested or in contact with the eyes. Take extreme care with this experiment.

How To: Make sodium bromate & potassium meta-periodate

This video tutorial is in the Education category which will show you how to make sodium bromate and potassium meta-periodate. This experiment uses toxic chemicals and releases harmful gases. First you have to make a saturated sodium bromide. To this solution then add a small amount of potassium dichromate. The solution now becomes concentrated. Then make the circuit as shown in the video. You need a 3 - 5 ohm resistor in order to reduce the current. Then let the cell run for around 6 hours. S...

How To: Make elemental sulfur (sulphur)

This video tutorial is in the Education category which will show you how to make elemental sulfur (sulphur). The chemicals you need are nitric acid and sodium thiosulphate. The reaction produces toxic SO2 gas so keep it coved with a watch glass. Put 12.9 grams of sodium thiosulphate in a beaker and dissolve it in minimum amount of water. Pour about 15ml of nitric acid in to the beaker. Let it sit in a warm place for a couple of hours and the sulphur will settle at the bottom of the beaker. Th...

How To: Make hydrazine sulfate with the hypochlorite and the Ketazine process

Hydrazine sulfate has many uses, but most notably, it's been used under the trade name of Sehydrin, a treatment for anorexia, cachexia and some even think cancer. But for we DIY chemists, it's useful for something entirely different— as a substitute for the more dangerous pure liquid hydrazine in chemical reactions. NurdRage shows you how to make it via some hypochlorite and the Ketazine process.

How To: Make your own non-toxic flea killer

Educational Specialist, Jennifer Taggard shows her viewers a very easy and accurate process to making non-toxic flea killer. This flea killer will not harm children in a household or any dog being treated. To make the flea killer, 1/2 of a cup of baking soda and half of a teaspoon of orange essential oil was used. The two ingredients were mixed together and simply applied and rubbed into the dog.

How To: Balance chemical equations using a teacher's guide

In this video we learn how to balance chemical equations using a teacher's guide. A chemical equation is a brief way of summarizing what happens inside of a chemical reaction. When you mix up two different chemicals, they will create new types of chemicals in the equation. You have to take these new chemicals into equation when you are trying to balance it out. The mass on both sides must be the same as well as the number of different chemicals on each side of the equation. Try out practice e...

How To: Balance chemical equations

n this tutorial, we learn how to balance chemical equations. This is a straight-forward concept to balance out both sides of the equation of chemicals. To start, you will need to analyze how many atoms in each chemical you have on each side. Once you do this, you will need to find what you can multiply by on each side to make them equal to the other side. Once you do this and have equal atoms on each side, then the equation will be equal. Remember that you cant have a half of an atom, so that...

How To: Balance chemical equations properly

In this video we learn how to balance chemical equations properly. What is a chemical equation? It's a statement that uses a chemical formula to show identities and relative amounts of the substances involved in a chemical reaction. To balance an equation out you must have the same number of atoms on both sides of the chemical equation. Or, you must have the same amount of mass or matter on both of the sides. Once you have these balanced out so they are the same then you will have it complete...

How To: Balance chemical equations with Olivia and Andrea

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...

How To: Balance chemical equations with ease

In this video, we learn how to balance chemical equations with ease. First, you will need to take down the equation and find out how it is formed and how much each of the chemicals are in it. Draw a diagram if you need to so you have a visual key. If you figure out how many of each of the chemicals are in the equation, then you will know how to balance it out. You will make sure that both the right and left have the same number of chemicals and mass. Balance this out by adding in more chemica...

How To: Make nitric acid

Watch this science video tutorial from Nurd Rage on how to make nitric acid. They show three ways to make nitric acid based on two different chemical approaches, both of which can be done using easily accessible materials.

How To: Understand chemical change in chemistry

In this video we learn how to understand chemical change in Chemistry. When you start out, you must first figure out what your cathode and anode is in the equation. Then, read it out to find out if it's oxidized. Once you have this figured out, you can find the conditions of temperature you need to maintain the chemicals. You can figure this out b doing a basic equation for all of the chemicals. Fill this in with the correct information, then the answer will be done. Make sure you understand ...

How To: Properly balance chemical equations

In this video, we learn how to properly balance chemical equations. You will see what substances are in each side of the equation. You will then need to count the atoms that are on each side of the chemical equation. Once you write down the number of atoms on each side, you will need to even them out. To do this, you need to change the coefficients within the equation. These change the total number of atoms inside of a chemical. Once you do this, you will add more to each atom present and the...
