Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.
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.
Glow sticks, a popular favor at parties and outdoor events, and a must-have on Halloween, can be traced back to the United States Navy in the mid-1960s. The military desired improved visibility during night operations, and glow sticks, with their small-size portability and lack of batteries, were a perfect tactical solution.
In this video, I'll be showing you how classic black snakes work and how to make them at home. There are actually two methods covered in the video — one that uses fire and one that does not. So just choose the one that fits best for your situation.
Glowing substances have always held a powerful appeal to people, and making new ones can be a lucrative business. If you need some glow powder for a project of yours, watch this video to learn how to make DIY glow-in-the-dark powder out of normal household chemicals.
Every day we pass bridges, whether it's a foot bridge, a highway overpass, a span over water, or a viaduct over a valley. We pass on these structures without even thinking of the engineering genius that went into their design and construction, let alone the science behind their strength.
Have you ever seen water freeze instantly? This "Quick Clip" shows some of my personal experiences with making instant ice using a bottle of water supercooled in a freezer.
Believe it or not, there are cheap ways to make potassium nitrate for your chemistry experiments. And the key ingredient… "sodium-free" salt.
One of the only things I remember from watching Nickelodeon as a kid is the epic green slime. Looking back, I don't know what was so great about it, but every kid my age thought that being drenched in slime would be the coolest thing on earth. Of course, the first thing I did was beg my parents to buy me some fake slime, but I never knew I could've easily made my own at home. One of the most common ways to make slime is to combine liquid glue with water and a household chemical called borax. ...
Interesting reaction coke and milk The reaction of phosphoric acid (V) to proteins in the milk - they are cut and causes a precipitate
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...
There's no reason to wait for Halloween to play with dry ice. It definitely creates a creepy fog-like effect when you add a little water to it, but there are some other really cool things you can do wit dry ice. Here are just 5 non-Halloween ways to use dry ice for tricks or pranks.
We all know what elephant toothpaste is, but what's the best way to make this massive growing foam? Dr. Lithium from NurdRage has answers. He'll show you the best way to reproduce this chemical reaction to get the best foaming action! This is a classic science class demonstration.
Want to make boring old colorless water brighten up on command? Well, you can control the color of water with this little magic trick. Actually, it's not really magic, but a classic science experiment known commonly as the iodine clock reaction, which uses the reactions between water and chemicals to instantly colorize water, seemingly by command. You can use different colorless chemicals to produce different colors, and you can even make the color vanish to make the water clear again.
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.
Sulfuric acid is mixed with sugar, which is attacked by the acid. The final products are carbon, water vapor, and sulfur dioxide gas.

All you'll need for this little science experiment or fiery weapon is 100% cotton cloth, scissors, lighter fuel, cotton string, and a needle. Be careful to follow the directions in this how-to video carefully otherwise you'll really be playing with fire.
Hmm... wondering what to do with a lazy Sunday afternoon? Why not build a volcano that can erupt? Have fun and make a mess, all in the name of science!
It's a stormy winter night, and you're electricity goes out. You could grab some candles to add a little light to your life, or you could use glow-in-the-dark chemicals for a cool luminescent.
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...
If you've been following the news lately, you've probably heard of the word "vitriol" being used as a political weapon, with people like celebrity left-winger Jane Fonda blaming conservatives like Sarah Palin for "vitriolic" attacks on Democrats and the "violence-provoking rhetoric of the Tea Party" movement for the recent Arizona shooting.

Enjoy viewing and detect...
Here we will demonstrate how to measure the volume of a balloon. A balloon is not a straight edged polygon shape, usually, so the mathematical equations get that much harder, on the flip side, it may be a spherical or ovalish shape, but measurements with math alone are detrimental due to the uneven sizes of the balloon. Here is how to do it properly. You will need a bucket, preferably, to hold water, a larger container than your original bucket, and a measuring container. Place the bucket ins...

Then add some soap into the vinegar and stir it by shaking the flask/baker. Users may choose to add some food coloring to make the mix look more like lava. In a separate, add some water and baking soda. Then stir it to mix. Pour the baking soda solution into the soap and vinegar mixture. This video will benefit those viewers who are interested in science and experi...
In this Education video tutorial you will learn how to do a yeast experiment to see how much C02 it produces with different types of food. Yeast is a fungus and it has to eat. After it eats, it produces CO2 gas. The bubbles in bread are produced by the CO2 gas from the yeast. Take five different types of food items and measure out the same quantity for each item. In the video it is 8gms of cookie, oil, flour, salt and sugar. Take six glasses of water and mix one packet of yeast in each glass....
Watch this science video tutorial from Nurd Rage on how to make hot ice with Dr. Lithium. This is the complete guide to making hot ice, more correctly called sodium acetate. See how to create it, fix it, and use it. All methods from baking soda and vinegar to laboratory synthesis are shown.
The trick in the video is that the magnets are made of a conducting material and they connect the battery terminals to the copper wire, so the battery, magnets and copper wire make a circuit that generates a magnet field just in the vicinity of the battery. The geometry means the two magnets are automatically at the ends of the generated magnetic field, where the field is divergent, so a force is exerted on the magnets.
