 First attempt after putting together the Foldscope. We had no idea what to expect. Our dog provided us with a small flea which we managed to stick onto the film. It might be the fleas’ stomach working or its heart pumping. No idea. We did not use the magnet to hold the sample to the phone (we were to impatient to keep watching what was going on inside the flea). Next time we’ll do things properly and it will be in class 🙂

Fleas’ heart? Fleas’ stomach working?
