water crystalsEnterprising gardeners mix these Water Jelly Crystals in with potting soil to help hydrate their plants, but Patricia Fernandez, director of catering at the InterContinental Tampa uses them for event décor. Drop them in water to turn them into jelly-like cubes, then stack them in a hurricane glass or vase, and the colors will blend together over the course of a few hours to create a rainbow. Buy them here; the set of red, yellow and blue, for $26.95, will create enough for an entire room.
