Description: We had observed a pinch of salt under the foldscope and we were surprised to see that apart from the miniscule salt granules, there was also minute sand particles mixed with it. The salt we had taken was common salt and it was disheartening to see that there were light brown sand particles in it. It’s safe to say that our salt vendors have been cheating us by mixing particles in our salt. The foldscope helped us observe this so easily!
