A student of mine, Anthony Shepherd, and I worked together to develop a new chemical riddle. How do you think we performed the experiment in the video below?

Here’s a great project to try with your students: build a periodic table out of Lego blocks. We did this a few years ago at Spring Arbor University, working with teachers and students from Hardin Valley Academy i
Did you know that Pyrex glassware used in chemistry labs is different than Pyrex glassware used in kitchens? Pyrex glass used in chemistry experiments is made of borosilicate glass, whereas the Pyrex used when baking is made of soda lime glass.
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.
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 i
Want to try an easy, yet interesting chemistry experiment this winter? Try this: Blow some bubbles into the outside winter air and catch one of the bubbles with a bubble wand.
