Over the past few weeks, two Ohio parents have become Internet celebrities for the 12-foot-high roller coaster they built for their kids out of PVC pipe. We are duly impressed. Though we build nearly 200 playgrounds a year, we have yet to build a roller coaster.
Do you know what's even more impressive? In California, a group of tweens and teens are building their own roller coaster at Gever Tulley's Tinkering School. That means they not only get to experience the thrill of the ride, but are also learning valuable construction and engineering lessons along the way.
