How To: Make Trippy Triboluminescent Crystals That Glow Red or Blue When You Smash Them

If you're a Breaking Bad junkie who can't wait for the next episode, satisfy your craving with a little at-home chemistry and make some blue DIY smash-glow crystals! No, this is not Walter White's so-called "Big Sky" or even the subpar cringe-worthy product of his competitors. It's not even the same kind of crystals, otherwise you wouldn't be reading this. This is totally legal, even kid-friendly if you play it safe, though it actually requires more safety precautions than the potassium nitra...

How To: Perform an ice-cube trick with sodium chloride

Think you can lift an ice-cube with nothing but a piece of string? In this cool how-to science lesson, Steve Spangler shows us how to do it, and explains what happens when salt is put on ice. We all know that salt is used to melt ice and snow, but do you know why? Leave it Steve Spangler to turn this basic science lesson into an after-dinner trick you'll use to amaze your friends.

How To: Make a ball float in the air

This video demonstrates Bernoulli's Principle which states that, “For an ideal fluid (low speed air is a good approximation), with no work being performed on the fluid, an increase in velocity occurs simultaneously with decrease in pressure or a change in the fluid's gravitational potential energy..

How To: Draw the Lewis dot structure for sulfate

TTUchme1010 teaches viewers how to draw the lewis dot structure for sulfate. The formula for this is SO4^2-. 2- means we will have to add 2 electrons into the lewis dot structure. First, we will have Sulfur in the middle with Oxygen surrounding it. Sulfur is in group 6A so it have 6 valence electrons and oxygen has six, so fill this all in around the elements. Now, you have to add in the 2 extra electrons onto the most electronegative atom. This will be oxygen. Now, you should start bonding t...

How To: Crush a soda can with heat and cold water

Want to find out how you can squash a can of Coke with a little science? Just watch this video tutorial to see how to crush a soda can with heat and cold water. You will need to get an empty can of Coke (or Pepsi if you prefer) with a little water inside, something to hold the soon-to-be-hot can with, a bowl, ice, water and salt. You can impress your friends with this trick, all without using your own force... a little chemical and temperature change goes a long way.

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: Dissect a sheep brain to compare to a human brain

This seven-part video tutorial will take you through the steps necessary to dissecting a sheep brain so we can learn and compare it to a human brain. You'll learn about the different kinds of memory in the brain, and that's not all. So, for this science anatomy of the brain dissection project, go down to the local slaughterhouse and get yourself a brain. Abattoirs are a great place for brains. Dissect a sheep brain to compare to a human brain - Part 1 of 7.

How To: Make a miniature vortex cannon

This is a video tutorial in the Education category where you are going to learn how to make a miniature vortex cannon. For this you will need normal plastic drinking cup, punching bag type balloon, black electrical tape, lighter, candle, scissors and a drill. Drill a hole in the bottom of the cup and cut off a big circle at the bottom. Cut the punching bag balloon in half and stretch it over the mouth of the cup and tape it up nicely. The cannon is ready. Now light the candle, hold the cup aw...

How To: Make ice cream and explore the ingredient salt

In this Education video tutorial you will learn how to make ice cream and explore the ingredient salt. Ingredients are a cup of milk, sugar, vanilla, some salt, ice and two plastic bags. Add two tablespoons of sugar to one cup of milk, a quarter teaspoon of vanilla, stir it up and pour it in to a plastic bag. Put this bag in another bigger plastic bag, add some ice and about half a cup of salt. Seal the bag and start mashing it. After about 10 minutes, it will turn into ice cream. When salt i...

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.
