This is common. The molecules are just looking for the easiest place to land. You can carefully pour the liquid into a clean jar and re-submerge your string to focus growth there.
If you’re impatient, this is the experiment for you. Epsom salts (magnesium sulfate) create delicate, needle-like crystals very quickly. 1/2 cup Epsom salt 1/2 cup very hot tap water A glass jar Food coloring (optional) A pebble or a few grains of sand (to act as a "seed") Instructions: growing crystal experiment

: Alum often forms clear, octahedron-shaped crystals (resembling two stacked pyramids). These are great for growing large, single "seed" crystals over several weeks. If you’re impatient, this is the experiment for you
As the solution cools or evaporates, the concentration of particles increases, driving the growth of the crystal. The crystal's shape and size depend on factors such as:
Drop in a pebble or a tiny bit of extra salt. This gives the crystals a surface to start growing on. Chill: Place the jar in the back of the refrigerator.
: Perfect for beginners, these form overnight on pipe cleaner shapes. Borax is highly responsive to temperature changes, making it ideal for "grown-in-a-day" projects.
