Learn a bit about the chemical reactions that occur during a lightning strike, and how you can demonstrate these reactions in your classroom.
Why does the "Whoosh Bottle" experiment behave differently at different temperatures?
The reaction of hydrogen and oxygen gases to form water is well known to be an exothermic reaction. That reaction can occur by first absorbing the hydrogen into palladium metal, and then placing the resulting palladium hydride into contact with oxygen in the air. Infrared and visible light videos were recorded for this process involving palladium foil, and the Green Chemistry and safety aspects of these activities are considered.
Chad Husting tries out some micro-scale labs.
Tom Kuntzleman conducts a safer "mercury-like" beating heart experiment with an added splash of gratefulness.

Can you use your knowledge of chemistry to figure out what is going on in Chemical Mystery #19?
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.
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.
