NurdRage is going to show you the steps for this makeshift potassium chlorate.
The first glow sticks were patented by the US Navy in the 70s, but back then, they were called "Chemiluminescent Signal Devices." Today, glow sticks are still used by the military, emergency services, campers, divers and, of course, ravers. I may be done with the glow-in-the-dark parties from my college days, but I still think glow sticks are pretty legit, and always thought it would be awesome to make some for myself. Talk about a cool application for all those boring chemistry lectures.
Believe it or not, there are cheap ways to make potassium nitrate for your chemistry experiments. And the key ingredient… "sodium-free" salt.

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.
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.
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. ...

Chlorine gas is a very useful oxidant, which was first introduced as a toxic weapon by the German Army. Even today, it's still used as a weapon, most recently in the Iraq War by insurgents. But chlorine gas has more useful (and less lethal) applications, and if you want to learn how to make some at home, NurdRage has the answers.
This video shows the viewer how to light an energy saving light bulb without plugging it in. The process is also explained in detail during the video. To light the bulb you need to inflate a standard balloon. Then rub the balloon over either a fabric or your hair. Then move the balloon back and forth near the light bulb. The bulb should glow dimly. This effect occurs because the balloon is negatively charged. This means that it has more electrons than protons. The video then goes on to explai...
If your microwave oven is broken, it might be because the diode has gone bad. If you think that may be the culprit, you might want to test it.
