Will Pemble's science education website CoasterDad.com has gone viral. Pemble's YouTube Channel and website chronicle the adventures of the now-famous backyard roller coaster builder Will Pemble, who designs and builds these privately owned amusement rides. While Pemble is the anchor, or host, of the show, the cast of characters varies from one episode to the next. Pemble's son, Lyle, an avid roller coaster fan and veritable encyclopedia of theme park trivia, contributes his expertise, leading site walks with other kids, and making design recommendations to his dad. "CoasterDad.com started when Lyle asked me to build a roller coaster in our back yard. I loved the challenge and the adventure of the project. Even more, I was amazed at the endless fascination kids had about the project. We turned our backyard into a worldwide physics classroom with kids lining up for learning," said Pemble about the genesis of CoasterDad.com.
