These are strings of an insoluble compound falling out of solution after a chemical reaction. The strings develop because the precipitate dissociates from the solution faster than the precipitate falls to the bottom of the reaction vessel.

Precipitates
Crystalline precipitates have less surface area than the colloidal precipitates, therefore they are more pure. Additionally, crystalline precipitates, because they are larger, are more easily separated from the surrounding solution.
No reaction. Precipitates generally form by a physical change called flocculation in which crystallization may also occur.
