Learn the chemistry behind the reaction between calcium carbide and water...melon...?!
Why does the "Whoosh Bottle" experiment behave differently at different temperatures?
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...
Build a propane gun for your students! Construction is inexpensive, easy, and the effects are spectacular.
My students and I intend to use a high-speed camera to film a variety of chemistry experiments in slow motion. The first reaction we have decided to film is the “Whoosh Bottle”. You can read more about this particular experiment in an article in Journal of Chemical Education here. NOTE: O
