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: 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 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: 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: Isolate the sugar in a can of soda

In this video from ScienceOnTheBrain we learn how to isolate the sugar in a can of soda. To find out how much sugar is in soda, pour a can into a pot and boil it until all the water is gone. You will be left with the sugar, and then you can weigh it. First weigh your pot before pouring the soda in. Now boil the soda on the stovetop. When the water evaporates, you'll be left with a syrupy sugar. A can of soda has 39 grams of sugar in it. That equates to about 7 1/2 teaspoons. Fruit juice conta...

How To: Ignite a Brillo pad

Check out this instructional science video to learn how to make a steel wool soap pad ignite. Using a 9v battery, touch the Brillo pad to make the steel wool ignite. This is a simple science experiment following step by step the instructions in this video tutorial, trying out for yourself. This is a great experiment to perform with the kids.

How To: Focus your laser to make it burn

In this video, we learn how to focus your laser to make it burn. The best spot for a laser to burn things is at its focal point. This is where the beam from the laser is at its smallest. If you hold a match in front of the beam, it will light it on fire as soon as it's in front of it. If you put two lasers next to each other going the same direction, it won't be able to burn because the light beam is too large. If you position the lasers so the light is smaller, then they can catch something ...

How To: Grow a crystal garden

A crystal garden is something that not everyone has. Grow a crystal garden for a science project, or grow it to add a hint of magic to your own herbal or vegetable garden. Show it off to friends and family. Watch this video to learn how to grow a crystal garden for your personal use.

How To: Weigh samples in the lab using a balance

The Interactive Lab Primer (ILP) has been developed as part of the Royal Society of Chemistry Teacher Fellowship Scheme, one of the themes of the Chemistry for Our Future program, and initiative which aims to secure a strong and sustainable future for the chemical sciences in higher education. The aim of the ILP is to address the diverse range of experience and skills students bring with them to a university by offering a resource to support their transition from school to the university chem...

How To: Make your own thin-layer chromatography (TLC) plates

The price of TLC plates can add up. See how to make thin-layer chromatography plates (TLC plates) for a few cents each that are as good as commercial TLC plates that sell for a dollar or two each. You can use these home-made TLC plates the same way you'd use chromatography paper, but the plates provide sharper separations and require far less analyte. They also lie flat, and are much easier to store for later reference. For more information, including step-by-step instructions, and to get sta...
