How To: Make a candle wax explosion
In this video, you'll see how and why wax can be a deadly. This is how it works,When the test tube is submerged in cold water, the glass forms tiny cracks. The Water enters gets into the tube and vaporizes causing a micro explosion. The hot wax is then ejected from the tube quickly as oxygen is displaced from the tube itself. Be careful, and make sure to be as safe as possible when trying this experiment at home.

How To: Draw atoms of different elements
An atom is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged ions. The nucleus itself is a mixture of positively charged protons amd electrically neutral neutrons. Different groups of elements have respective atomic numbers. You can use the periodic table as a tool to draw atoms of elements. The periodic table is organized into periods, groups and families. This video is a tutorial that reviews the subatomic particles found in an atom. I...
How To: Make dancing drops
This video shows you how to make your liquid dance. Its happens like so, at around 300 degrees Fahrenheit a phenomenon in which a liquid, at close contact with a mass significantly hotter than the liquid's boiling point, rides upon an insulating vapor layer which keeps that liquid from boiling and evaporating. What is this strange phenomenon? The "Leidenfrost effect" of course, and with Mr. G at the helm it's also a lot of fun.

How To: Calculate and understand the concept of molar mass
Two college students; Kevin Martin and Joey Smokey introduce the concept of Molar Mass. They start of by explaining what molar mass is, which is the relationship of a mole and a gram, it totals up the weight(in g)of a molecule. An example: say you have this compound, Sodium phosphate (Na3PO4). You know you have three sodium atoms, one phosphorus atom, and four oxygen atoms. You basically find the weight of each atom, if you have three sodium atoms, you multiply it's atomic mass by 3 (the numb...

How To: Make hot ice from scratch
To make instant hot ice or sodium acetate, first pour two jugs of vinegar minus one cup into a large pot. Then, slowly add baking soda to the mixture and stir it. When the vinegar and baking soda no longer react, stop adding baking soda. Next, add the rest of the vinegar to the pot. Boil half of the solution off and cool it down to room temperature. For better filtering, add charcoal to the mixture. Filter out the charcoal with a wire sifter. Heat up the solution again and filter it through c...

How To: Balance chemical equations with MyTutorBuddy
Learn how to balance chemical equations with MyTutorBuddy. Learn about this in this video tutorial. There are four easy steps to do this. Step #1 – place 1 by the most complex compound. Step #2 – balance anything that is not an element. Step #3 – balance the elements. Step #4 – multiply by the lowest common multiple. The 4th step doesn’t always come in to play. The video demonstrates with an equation: C3H8 + O2 -> H2O + CO2. But, this equation is not balanced. Using the 1st three steps, the v...
How To: Make a simple ping pong smoke bomb with one ball
This video demonstrates the easiest and fastest smoke bomb that a person can make. Supplies include aluminum foil, standard ping pong ball, a pen or pencil, and a flame lighter.

How To: Balance chemical equations with Olivia and Andrea
Olivia and Andrea created a song to the tune of "I'll stand by you" by the Pretenders to teach you how to balance chemical equations. A chemical equation requires coefficients in order to be balanced. You can balance a chemical equation by making use of the Periodic table. The example reaction in the song is that of aluminum and oxygen to produce aluminum oxide (Al + 02 -> Al203). You can systematically add coefficients to the reactants and products to balance the equation. A chemical equatio...

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: Understand different immune system responses
This is a presentation of different types of immune responses in human body. There are two types of immune systems i.e., non specific and specific or adaptive immune system. Again, non specific immune system is sub- divided into barriers. It is the first line of defense. The second line of defense is the inflammatory response. They are phagocytes. These are all products of white blood cells. It is also called as leukocytes. Lymphocytes are another type of white blood cells which are carriers ...

How To: Purify manganese sulfate contaminated by iron sulfate
In a previous video by NurdRage, he showed you how to make manganese sulfate ("How to make MnSO4 from MNO2 (two separate ways)"), but there can be situations where the iron in the precursor would carry over and contaminate the product. Recrystallization doesn't work for this high level of contamination, so a different approach is needed.
How To: Understand how helicopters work
Ever wonder how helicopters work? Gather a piece of paper, a ruler and a pair of scissors. Take the ruler and draw 3 lines of 10cms on a sheet of paper. Then place the ruler in the middle and draw 2 lines of 14cms in length. Then cut the lines with the scissors and fold the slides in the opposite direction. Get one paper clip and put it on the tail end of the helicopter. The flight of the helicopter depends upon the size of the wings. It will help you to learn the dynamics of a helicopter.
