Images-9 Please have this kid contact MAKE – A 14-year-old German boy has been ordered to pull down a 300ft long roller coaster which he built in his backyard. The boy, unnamed due to German privacy laws, from Offenburg built the 16-foot-high wooden construction over the summer holidays. He even designed his own carriage which can reach speeds of up to 30 mph. But local town planning officials say he must pull it down again because he did not ask for planning permission. They say the construction is too large and not built to rollercoaster safety standards. The boy has until mid-September to tear it down if he wants to avoid a fine. Link.
