Put pieces of charcoal, brick, or cement into a bowl, and add two tablespoons each of water, salt, and liquid bleach. Add two more tablespoons of salt the next day. The third day, pour two tablespoons each of salt, water, and bleach in the bottom of the bowl. Crystal formations will appear that resemble coral polyps, which make up coral reefs.
