The Denver Museum of Nature & Science is asking Twitter users to talk to a plant to keep it alive.

To support its exhibition MythBusters: The Explosive Exhibition (running until January 6th), the museum, and agency Carmichael Lynch, is running a Twitter experiment to test the well-established "myth" that talking to a plant helps it grow stronger and healthier. To take part, they need to visit the website talktoaplant.com and send the plant a tweet (about whatever they like). A custom tweet-to-speech technology, developed by the agency using an Arduino-based device, will then read their tweet aloud to one of the plants. Another plant will sit in silence and the two will be compared over the course of the next couple of months. The website carries infographics on plant growth, words heard and leaf color and size, as well as recording all the tweets.

In 2008, Heinz tried to replicate that famous experiment as well, via a site that let people type in words of encouragement that were played through speakers to plants housed inside a lab.
