How To: Make maganese heptoxide (permanganic acid)

This video tutorial is in the Education category which will show you how to make manganese heptoxide (permanganic acid). This procedure is extremely dangerous. Manganese heptoxide is an extremely powerful oxidizing agent. It has the ability to set fuels on fire from mere contact. Get an old dish and put a spatula full of potassium permanganate on it. Add a few drops of concentrated sulphuric acid. A green liquid is formed which is the manganese heptoxide. Now you can add any fuel like butanol...

How To: Make hydrochloric acid from salt

In this tutorial, we learn how to make hydrochloric acid from salt. First, you will pour some salt into a distil flask. After this, you will add in some concentrated sulfuric acid to the salt. Next, you will let these react with each other. You will start to see gasses bubble up and the excess hydrogen chloride gas come out through the top of the tube. To create a stronger reaction, you can add heat underneath the reaction. Then, test this by exposing it to ammonium chloride. If it's the righ...

How to Be Your Own SpaceX: Design, Build & Test Liquid-Fueled Rocket Engines

Move over NASA— SpaceX is taking over. Well, not really. But today, the privately funded spacecraft company broke all expectations when their Dragon capsule fell to a soft landing in the Pacific Ocean, completing an undoubtedly successful demo flight of nearly two full trips around Earth. It was the first re-entry of a commercial spacecraft ever, bringing commercial space transportation closer to reality.

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: Experiment the law of inertia

Newtons proposed the concept of inertia. According to him an object at rest tends to stay at test and an object in motion tends to continue in motions unless acted up on by an external force. This is the principle of inertia. The tendency of the body to continue to stay as it was is called its inertia. You can demonstrate this principle with a simple experiment. As shown in the video when the hoop is pulled out the pen cap falls in to the bottle. Here the hoop is acted upon but the cap is not...

How To: Make iodine easily

In this video, we learn how to make iodine easily. You will need potassium iodine and sulfuric acid to make this. First, add the acid into the potassium iodine slowly. After you add in each part, swirl the beaker slowly so it gets mixed together. After you have added in all of the potassium, you will place this into a beaker filled with ice water while you add in more, because the mixture gets really hot. When finished, you will end up with a mixture that is iodine and nothing else. Fill with...

Classic Chemistry: Colorize Colorless Liquids with "Black" Magic, AKA the Iodine Clock Reaction

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.

How To: Make Potassium Chlorate from Ordinary Household Bleach and Salt Substitute

If you're not just a chemistry nerd, but also a firearms freak and explosives nut, then this home brew chemistry concoction is just what you need for some cheap homemade potassium chlorate. It's a mixture of potassium, chlorine and oxygen (KClO3) and is used for such things as gun primers, propellents, and explosives (when mixed with the appropriate fuel). And guess what? NurdRage is going to show you the steps for this makeshift potassium chlorate.

How To: Use a Peltier module to create free electricity from heat

A Peltier module allows you to turn heat into electricity. Because you can place it in areas that are normally warm anyway, the electricity created is "free" in a sense, though it does work best when one side of the module is cold and the other is hot. In other words, all you'll need for this project is the Peltier module and a cooler surface such as soil or water, and a warm area such as a well lit window or warm pan.

How To: Use baby powder to reveal latent fingerprints

This short video shows us how to reveal latent fingerprints on a glass surface by dusting. Anyone interested in forensic science would enjoy trying it as it shows simple steps in dusting and lifting fingerprints. It does not require any chemicals and we can do it with baby powder. The steps involved are so simple and easy to follow that even kids can try it out for fun. This gives a clear idea about fingerprints on different objects like porous, non porous and metals. Enjoy viewing and detect...

How To: Make crystal iodine

MAKE brings the do-it-yourself mindset to all the technology in your life. Make Magazine celebrates your right to tweak, hack, and bend any technology to your own will. In this tutorial, Robert Bruce Thompson shows you how to make crystal iodine. As Thompson says in the video, crystal iodine is currently a schedule one compound, and in order to buy you have to fill out a lot of paperwork and you'll end up on a DEA list. This tutorial gets you around that, but proceed carefully.

How To: Make Your Own Homemade Glow Sticks

Glow sticks, a popular favor at parties and outdoor events, and a must-have on Halloween, can be traced back to the United States Navy in the mid-1960s. The military desired improved visibility during night operations, and glow sticks, with their small-size portability and lack of batteries, were a perfect tactical solution.

How To: Make boric acid from borax

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...

How To: Extract DNA from a banana

Check out this instructional science video that demonstrates how to extract DNA from a banana. This is a great science experiment for students and kids to perform by following the simple step by step instructions outlined in this science tutorial video. Extract real DNA from a banana and analyze it under a microscope.

How To: Make hydrogen gas & an explosion

First you need to make hydrogen gas which require a few material. Such as a glass bottle, a Full table spoon of aluminum (beer or soda can will work), a half a cup of cold water, a table spoon or two of caustic soda, a funnel, a medium size container of water, a way of cutting the aluminum, one or two balloon's, and some safety glasses just incase something goes wrong.

How To: Compare fractions.

This video will show those who would like to learn more about math how to easily compare fractions with different denominators using a simple technique. You will be able to compare the fractions to each other by multiplying the numerator of each fraction with the denominator of the other, in a process called cross-multiplication. Keeping the numbers on the proper side of the equation, compare the two products which you receive from each cross multiplication and you will be able to compare the...

How To: Measure the volume of a balloon

Here we will demonstrate how to measure the volume of a balloon. A balloon is not a straight edged polygon shape, usually, so the mathematical equations get that much harder, on the flip side, it may be a spherical or ovalish shape, but measurements with math alone are detrimental due to the uneven sizes of the balloon. Here is how to do it properly. You will need a bucket, preferably, to hold water, a larger container than your original bucket, and a measuring container. Place the bucket ins...
