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.
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...

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...
Now we explain how to marinade and barbecue on the grill. Skill level is beginner. For great-tasting chicken, consider whole chickens over light or market chicken parts.

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.
