Have you ever wondered why dust seems to make most most people sneeze? There is a fairly obvious reason for this annoying little problem (if you have a foldscope). As you can see in this picture, dust has very many little particles in it. I assume that some of those little particles are pollen, bacteria, and dirt, all crammed into one annoying sneeze maker. This is my last foldscope entry so it’s kinda bitter sweet. I’ve learned so much from this useful little resource and I’ve also had a lot of fun in the process. THANK YOU MANU!!!!!!
