The "Two-Faced" thionin reaction involves causing a purple solution to fade to colorless by shining light on the solution. I wondered if it could be demonstrated the color of light that caused this transition.
Did you know that sand can be converted into a mixture of gases that spontaneously ignites in air? The procedures involved are relatively simple to perform, spectacular to observe, and relate to a rich assortment of chemical principles.
The Ruben's Tube (also known as a Flame Tube) is a classic experiment used in physics classes. There's also a bit of chemistry to be learned while experimenting with a Ruben's Tube...
Chemistry and lasers can be used to create a demonstration that includes several colors and flashing lights. This demonstration connects to topics in quantum chemistry and phase changes.
This post describes some simple experiments using various coins and neodymium magnets that connect to the 2019 National Chemistry Week theme of Marvelous Metals!
The June, 2018 issue of the Journal of Chemical Education contains an article that describes a simple, yet fascinating experiment that you and your students are going to love! It involves the use of butterfly wings from the genus Morpho. I obtained some of these wings and enjoyed experimenting with them. You will too!
You are likely aware that diamonds are converted - albeit slowly - to graphite under normal conditions. Thus, diamonds don't last forever, in contrast to the popular advertising slogan. However, did you know that you can use chemistry to prove that diamonds are not forever? It's simpler than you think...
Simple methods to prepare liquid air are described. In addition, ways to test the properties of liquid air and other liquefied gases are explored.
The solution to Chemical Mystery #11, which involves the Leidenfrost Effect, is presented.
What happens if you place metal that is glowing orange-hot into some water? Watch this video and find out!
