I am doing a science experiment that I got out of a book. The experiment was to grow "stalagtites and stalagmites" on a string by using Espson salts. I followed the instructions: filling 4 glasses with water and salt solution, then placing a black yarn from one glass to another making an X. The crystals were supposed to form on the string making a "stalagtite" and then dripping onto the surface making a "stalagmite". The problem is that the crystals never formed on the string, but started forming in clusters on the outsides of the glasses. I did the experiement twice with the same results. Why would the crystals form on the outside of the glasses instead of the yarn?
