This Pumpkinator is a fantastic orange-to-blue-to-orange chemical reaction that will make a great addition to your Halloween-themed chemistry demonstrations.
Oxidation / Reduction
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.
Tom Kuntzleman conducts a safer "mercury-like" beating heart experiment with an added splash of gratefulness.
Inspired by a recent article in the Journal of Chemical Education, Tom Kuntzleman attempted to extract lithium from a coin battery, and to use the extracted lithium to produce a pink flame.

Beautiful, metallic mirrors of copper or silver can easily be formed in test tubes. Simply add the appropriate metal salt to a test tube, and heat! These reactions should be performed in a fume hood.
Learn how to give pennies a beautiful, silvery-colored plating.
Tom Kuntzleman tests to see if Powerade can be used as a source of reducing sugars in the classic silver mirror demonstration, and reminisces about Christmas days past when doing so.
Simple chemical tests are described that can indicate the presence of certain metals in coins. A wide variety of chemical concepts are involved. The experiments described are a natural fit for the 2019 National Chemistry Week theme of "Marvelous Metals!"
In this blog post, I would like to share a relatively simple demonstration you may use to introduce the concept of antioxidant along with its potential in everyday life.
