How To: Do an acid grind on rollerblades

Kyle of Aggressivemall teaches you how to land an acid grind with aggressive skates.You should first go to your favorite curve to practice it as a stall. When doing an acid grind, your soul foot (or the one you use for balance) is placed along the grind bar and the other foot is placed like in a backslide. Once you get comfortable with the stall, you can start practicing the grind itself. For starters, you should approach the grind bar with a slight angle and moderate speed. While grinding, b...

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 Ferrofluid: The Liquid of the Future

What Is Ferrofluid? Ferrofluid is a black, solvent-based liquid, that, in the presence of a magnetic field, becomes strongly magnetized. The fluid is made up of nanomagnetic particles coated with an "anti-stick" or surfactant compound, suspended in a "carrier", commonly an organic solvent. For mechanical applications, it is used in hard drives and speakers as a lubricant. However, it also has been implemented in artwork, as seen in the video below.

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: 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: Understand organic molecules & elimination reaction

This video helps us understand the organic molecules and elimination reaction. Take some sugar in a beaker. Sugar has 12 carbon atoms, 22 hydrogen atoms and 11 atoms of oxygen. The sulphuric acid is poured into the sugar and the color change is observed. The color of the sugar gradually changes into black. The sulphuric acid causes an exothermic reaction which releases a large amount of sulphur dioxide gas. All the water (containing hydrogen and oxygen atoms) is eliminated out of the sugar du...

How To: Marinate and barbeque chicken on the grill with Lowe's

Cook for 10 minutes on one side at medium heat. Cook on the other side for another 5 minutes and check the temperature. If the temperature is at 165 degrees it is...

How To: Make a penny operated nitric acid fountain

Watch this video to learn how to make a penny operated nitric acid fountain. Nitric acid acts upon copper to yield nitric oxide in an exothermic reaction. The expanding gas displaces water from another flask; actually bubbles in this set up. When the gas cools, the water is drawn back into the flask, dissolving the nitric oxide and forming a blue solution with the copper ions still there. Very cool science experiment with a neat reaction.

How To: Understand chemistry & chemical change

This video tutorial is in the Education category which will show you how to understand chemistry and chemical change. The question here is 10g of Mg ribbon reacts with 0.15 mol decimeter cubed of hydrochloric acid at 25 degree Celsius. What is the balanced equation for this reaction? When magnesium reacts with hydrochloric acid, you will get magnesium chloride and hydrogen. So, the equation will be Mg + 2HCl = MgCl2 + H2. Mg is in group 2 of periodic table and has a valance of 2, whereas Cl i...

How To: Make green fire from household materials
