Haha this is such a weird experiment I did. I really love the idea that physics education could be like a fantastic fantasy quest where you use physics to solve problems.

One day, lost in the woods, Kip came across a fairy with a mischievous glint in her eye. She looked like the type of person who would know her way out of the woods. He had been lost for many weeks, and he hoped this fairy would tell him the way out of the gloomy forest. Not in the least because there was something with glowing red eyes following him. But the fairy refused, unless Kip could correctly answer her questions.
