And why should you know?
What is she doing in the lab, you ask? Isn’t that dangerous? Who let her in there? Don’t worry! I’m nowhere near a laboratory and these pictures are actually from my sister. For some reason, she became a talented scientist and is currently writing her bachelor thesis in nanoscience with a specialisation in organic chemistry. And she is doing pretty cool stuff and I only understand half of it. But I do understand the part about fluorescence and it’s not only pretty but also very useful.

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!

Thoughts about the energy concept
Let’s talk about energy. But don’t despair, this won’t become too theoretical. I promise. All I want to do is to nudge you into the right direction of thinking about energy as a concept that can explain many things in everyday life. Because that’s all there is to it. Obviously, the last sentence isn’t true, as energy is still something worth researching. But the technicalities are not important, but how we think about it is. So let me give you an example.
