iPhone Time Lapse of Pine Cones Closing and Opening
Published on May 5, 2013
Filmed on iPhone 5 using TimeLapse app. It took about 2 hours for the pine cones to close and about 8 hours for them to even start opening. The clip I used in the second part of this is a 4.5 hour period during the drying process. I put one in a wine glass to see if it would open inside and get stuck - but the glass made it dry slower and it didn't open much at all.

To generate motion, plants and some seeds harness the supply or deprival of water from tissues. Scientists mimicked the process, making a tiny plant-inspired robot that moves via changes in humidity. In the future, medical robots powered by humidity could disinfect wounds, remove skin wrinkles, and nourish skin tissues.
