Wow students with the Halloween clock reaction, also called the Old Nassau reaction. This color change reaction goes from orange to black.

YOU WILL NEED Sometimes it’s hard to tell SCIENCE from MAGIC – and this little demonstration is a great example of that. In this experiment you will watch an almost clear liquid suddenly turn dark blue in a flash. It takes a bit of preparation, and probably a trip to the pharmacy for materials, but …

The Iodine Clock Reaction is classic chemistry in action. And it is amazingly simple. You can by a kit from a number of different science websites...or you can just go to your local grocery store to pick up basic supplies. You can use simple chemicals that you can find nearly anywhere, like vitamin C, iodine, hydrogen […]

As well as being a science geek, I’m a magic geek. I’m not sure if anyone’s done the research on this, but I suspect those are two groups of people where there’s a significant overlap. I’ve got an entire live science show I do based around my love of magic and my somewhat lame attempts … Continue reading Magic in the classroom: The Iodine Clock →

This is what an iodine clock reaction looks like

When three clear solutions are combined together, the mixture remains colorless for a few seconds, then it develops a bright orange precipitate and finally, ...

Iodine clock reaction uses chemical kinetics, 1st there is no reaction, then it turns to dark blue. Don't BLINK! or you will miss it!

Instant Color Change Experiment | Iodine Clock Reaction: In this project, we will turn almost clear liquid into the dark in the blink of an eye. It takes a little preparation, and possible trip to the pharmacy, but it's worth it. https://youtu.be/cB87Cyxqtg8
