Description

When a piece of metal salt is dropped in the solution of sodium silicate, a membrane of insoluble metal silicate is formed. Due to the osmotic pressure, water enters the membrane and breaks it, generating more insoluble membranes. This cycle repeats and the salt grows into all kinds of interesting forms. This film recorded the osmotic growth of 6 salts inside sodium silicate solution. The growth is so life-like, no wonder Stéphane Leduc thought it might have something to do with the mechanism life over 100 years ago.
