Oil spill? Take beeswax capsules

Beeswax microcapsules designed to keep out water, but absorb oil have been designed by NASA and others to clean up oil spills. The capsules contain micro-organisms that “eat” oil when it seeps through the beeswax shell.

When the balls are full of digested oil, they explode, releasing enzymes, carbon dioxide and water — all environmentally safe and reportedly even good as fish food.
