Nail Bottle Demonstration in Slow Motion

The nail bottle demonstration is one that many of us have conducted in our classes. To perform this demonstration, 2 – 3 mL of ethanol is placed into a plastic bottle that has two nails punctured into opposite sides of the bottle. After stoppering the bottle, a Tesla coil is touched to one of the nails. A spark jumps from one nail to the other, which initiates the combustion of vaporized ethanol inside the bottle. We recently filmed this reaction with our high speed video camera.

Whoosh Bottle, take 1

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

Social media brought me here

By way of introducing myself, I'd like to respond to Deanna Cullen's blog post about social media here on ChemEd X with some ideas of my own. The reason I'm here is that Deanna found me through following one of the chemistry-related Twitter chats and invited me to join ChemEd X as a contributor. I currently teach IBDP Chemistry at the American International School of Bucharest. Since my early days as a teacher, I have utilized technology throughout my instruction. I also incorporate some ideas from the modeling chemistry movement to help my students understand chemistry at the particle level. I'm hoping to share some ideas that will inspire you to try new things, and I'm also expecting to learn a lot from all of you that interact with us here at ChemEd X.

When the outside temperature drops below 0°F (-18°C), the conditions tempt this experiment!
