Wake Forest University Students Design Bottle Tower for Earth Day

Wake Forest University students are busy erecting a tower made of 2,000 plus bottles for Earth Day. This project, which reuses old plastic bottles, will serve as a "pledge collector" at the Annual Piedmont Earth Day Fair on Wake Forest's campus. Visitors to the fair will be invited to write down an environmental pledge and insert the piece of paper into the tower. To get an idea of what such a structure might look like, Wake Forest students have provided pictures from past examples of bottle towers, which you can check out on their facebook page for the project.
