Ocean scientist Andrew David Thaler has cooked up a clever DIY science project that lets people simulate the effects of ocean acidification using supplies that are available in their own homes. Of course, you will need a carbonic acid reactor (better known as a soda stream).

"As this experiment continues, it will develop into a series of lesson plans for science teachers to use in the classroom," writes Thaler over on Southern Fried Science, where he announced the experiment. Head over there for more info on how to get started, to track the project as it develops, or to follow along with your own miniature ocean.
