In 2006 the very first Physics Bus travelled from Tucson, AZ to Boston, MA and back again. Powered by veggie oil and a love of physics phenomena, our team of science & math educators and students were on a mission to visit as many science centers as we possibly could. This trip kicked off the creation of a video and photo database of physics exhibits from over 30 (still growing) science centers. Since then, many exhibits have been recreated aboard seven Physics Buses. Now this database is a useful resource for students building exhibits as part of PHYS 4500 at Cornell University.
