Electrochemical fuel cells as a science toy

Explaining energy conversion efficiency and combustion

You probably already know that I write a lot about physics experiments. But I also love science toys and today I want to talk about something more chemical than physical. Obviously, the electrochemical fuel cell cars I am talking about can (and in my opinion should) be included in physics education, because talking about energy conversion efficiency in real life and authentic settings is so valuable. The big advantage of fuel cell car toys is that they combine fun with science with real interdisciplinary science learning. See for yourselves!

Graduation Towers and saline solutions

What does evaporation have to do with spa towns?

As you might have noticed by the lack of an experiment last week, I’ve been on a vacation and enjoyed some time away from work, Instagram and my blog. But I can tell you – my mind never wanders far from fascinating physical phenomena and so when I went on a stroll in the region I grew up with, I came across the graduation towers and enjoyed the fresh breeze filled with salty smell just like the ocean. We used to go there often when I was a kid and I really enjoyed talking a walk there. They don’t have anything to do with a school graduation but are used for increasing the concentration of saline solutions. And that’s exactly what I want to talk about today, so this will be a more theoretical blogpost with a little chemistry and physics backgrounds. Enjoy.
