At the center of the exhibit is Bug Towers, a condominium for insects that was build out of wood, bamboo and plastic bottles, reported The Scotsman Saturday.

Also popular with attendees has been Renew, a vegetable garden created out of recycled materials by Barony College. "We wanted to show people that with a bit of effort and not a lot of money you can create a vegetable garden. We begged, borrowed and recycled and the whole garden cost us about 10 pounds (about $20) to make," explained Brian Connelly of Barony College.
