Chlorine gas is a very useful oxidant, which was first introduced as a toxic weapon by the German Army. Even today, it's still used as a weapon, most recently in the Iraq War by insurgents. But chlorine gas has more useful (and less lethal) applications, and if you want to learn how to make some at home, NurdRage has the answers.
In this home scientist video the instructor Robert Bruce talks about cheap sulfuric acid. He says that sulfuric acid is very important in any lab both as a reagent and a precursor for preparing other chemicals. He points to the battery acid saying that it is a good source of sulfuric acid which is 35% concentrated. Now he shows various methods to obtained sulfuric acid and shows how to test one of the thus obtained sulfuric acid for its concentration. In this video the author talks about sulf...
Nitrogen Triiodide is a very powerful contact explosive, but like most fun chemicals is not readily available to the general public cheaply. If you want some and have some chemistry skills, watch this video to learn how to make Nitrogen Triiodide at home out of household ammonia and water purification iodine crystals.
This is a video tutorial in the Education category where you are going to learn how to make boric acid from borax. For this experiment you will need borax (disodium tetra borate) and conc. hydrochloric acid. Take 25 ml of hydrochloric acid and dilute it with 75 ml of water. Next take 6 - 7 gms of borax and dissolve it in boiling water. Now add equal amount of hydrochloric acid. Crystals of boric acid will start forming. They are completely insoluble in cold water. After about half an hour, fi...
Unless you're a high-schooler building a nuclear fusion reactor, the hardest part of a science investigatory project often is coming up with a good idea. You want it to be cool yet feasible, novel but still useful.
This flame you CAN hold, without burning your skin off. Learn to make fireballs you can hold in your hand. This amazing video tutorial shows you how to do it. All you'll need for this little science experiment or fiery weapon is 100% cotton cloth, scissors, lighter fuel, cotton string, and a needle. Be careful to follow the directions in this how-to video carefully otherwise you'll really be playing with fire.
Learn how to make iodine with readily available materials with Phil Torrone in order to avoid being on the DEA's list.
This video topic was changed. It is now converting muriatic acid to reagent grade hydrochloric acid, HCL).
This video illustrates how to make napalm. You will need a petri dish, gasoline, and styrofoam to create napalm. Combining the styrofoam and gasoline in a petri dish you allow the styrofoam to dissolve and become a semi-solid substance. It will have the consistency of chewing gum and it will be highly flammable. This substance will be sticky and if lit it should be lit outside and at a distance from anyone as it will produce a gas that is toxic.
If you put mothballs in a solution of vinegar and baking powder, the balls will collect air bubbles; then after they cause the balls to rise, the bubbles pop, and the mothballs drop.
This video is an excellent example of how to demonstrate the doppler effect in the classroom.

MrfixitRick shows how to make hydro-electric power using faucet water pressure, a Tesla CD Turbine, and a Subaru radiator fan motor.
Want to make boring old colorless water brighten up on command? Well, you can control the color of water with this little magic trick. Actually, it's not really magic, but a classic science experiment known commonly as the iodine clock reaction, which uses the reactions between water and chemicals to instantly colorize water, seemingly by command. You can use different colorless chemicals to produce different colors, and you can even make the color vanish to make the water clear again.
Watch this science video tutorial from Nurd Rage on how to make potassium nitrate from instant cold packs and potassium hydroxide.

Make a reusable glow stick, glow-in-the-dark-style! Imagine, you'll never have to buy one of those ChemLite's again, because you can reuse this homemade glow stick over and over again. This video tutorial will show you how to make a permanent, reusable glow stick. The materials in this experiment are simple: epoxy resin, straw, and some phosphor powder.
Creating awesomely messy slops of DIY slime and curdled fake blood isn't something new—we even have guides on making Dr. Seuss-friendly Oobleck and the radioactive green ooze that created my childhood favorite Teenage Mutant Ninja Turtles (minus the radioactive part, of course).
You can do all kinds of unexpected things with milk, like make your own pore strips and invisible ink, or even get rid of red wine stains with it. But did you know that you can also use it to make your own glue?
Chemistry can be very fun when you create different kinds of reactions between elements. Note that caution should be employed to not harm yourself while performing these reactions. Ammonium Tricynate reacts with barium hydroxide octahydrate in endothermic form. Endothermic reactions are those which absorb heat from the surroundings during the reactions as opposed to exothermic reactions which produce a lot of heat during the reaction. When endothermic reaction occurs, depending up on the inte...

A balloon's worst fear is a sharp object, so usually when you puncture a balloon, it pops in your face. Not with this science trick! To puncture a fully blown up latex balloon without popping it, you'll need a pointed metal or wooden skewer and some plain old dish soap. That's it.
In this home-science tutorial from WonderHowTo favorite Nurdrage, you'll learn how to create hydrochloric acid using 140 grams of sodium bisulfate, a pH lowering compound available in most pool stores, and 60 grams of sodium chloride salt and an external heat source. Watch for a full demonstration of the process and complete, step-by-step instructions.
In this tutorial, we learn how to reveal latent fingerprints on paper & other surfaces. The item you will need to do this is crystal iodine and plastic sheeting to protect your work surface. Place your specimen into a plastic container with the iodine, then put the top on and let sit, placing your hand under to warm it up. Within a few minutes you will see a violet color vaporizing in the container. When finished, you will be able to take out your specimen and see the fingerprints that are al...
In this video Dr. Carlson does several experiments to illustrate how a vacuum works. A vacuum is created when all the air is removed from an object.
This is how to make a near professional grade lava lamp. We did this as a chemistry project. We perfected it in a week. This took many hours to do, as we had to get the density just right. We remade it three times, also. At the very end, we combined all of the wax into a huge flask. And then it blew up.
Now you see it, now you don't! Team up with the science sleuths of A-TV to make your own invisible ink.
In this video, we learn how to use a protractor to measure the height of any object. First, attach a level to the protractor, followed by a straw at the 45 degree angle. Next, walk back form the object while looking through the straw. Keep walking back until you spot the top of the object through the straw, then measure to the base of the object. After this, you will have an isosceles triangle that has two equal sides. Use these sides to help find what the size of the object is. After this, a...

In this tutorial, we learn how to create an erupting volcano. First, take ammonium dichromate and pour it into a clear plastic dish. Next, grab a blow torch and blow it onto the material. This will make a substance that is black and looks like ash. This will get messy, so make sure you have a newspaper or cloth underneath the dish. Eventually, the material will catch on fire so you can remove the blow torch, then the ash will fall all around the volcano and the sparks will fly out of the midd...
