"Smart Korean designer Sungwoo Park came up with a simple solution for wet benches and chairs. It is built on a rotating axle. Just turn the hand crank to unveil the dry side of the seat so you can take a load off without getting a wet behind.

SIdenote: I apologize for my inactivity on the blog and for not handling my responsibilities regarding the theme of the park but I have hardly found any time to relax properly because of school work and college applications. The bulk of my applications are done and one of my school competitions is next week so I will be contributing more to the blog and to the team from now on.
