 Well, some time ago I was experimenting with the foldscope LED position and their effects on a sample of water from irrigation canal, and I discovered that some rectangular things shine and change their colors, I ask to official Foldscope Instagram account what that things could be, and Manu said “that’s a diatom”.

 So this is all my diatom stuff, enjoy it 🙂
