LOS ANGELES, May 31, 2013 /PRNewswire/ -- The California Science Center, in partnership with Toyota Motor Sales, U.S.A., Inc., unveiled the Toyota Tundra full-size pick-up truck used to tow the Space Shuttle Endeavour over the 405 Freeway Manchester Boulevard Bridge during its journey through Los Angeles and Inglewood Streets. The Tundra is on display as part of the Giant Lever Exhibit, located in the California Science Center/California African American Museum parking structure adjacent to the science center entrance. The unveiling commemorated Endeavour's last flight STS-134, which launched May 16 and landed in the early morning hours of June 1, 2011.

Five year-old "future astronauts" Noah Lara and Samantha Comiskey, dressed in orange jumpsuits, demonstrated the science behind the Giant Lever Exhibit. A lever consists of a rigid beam pivoting on a fulcrum. By standing further away from the fulcrum, the two applied less force and were able to lift the Tundra full-size pickup truck. "We are thrilled to unveil the Toyota Tundra as an addition to our Giant Lever Exhibit, as we commemorate the anniversary of Endeavour's last mission," stated Rudolph. "We are grateful for Toyota's longstanding commitment to science learning." In addition to the donation of the Tundra, at the unveiling, Rouse presented a check from Toyota's Tundra Endeavour Tweet Drive to the California Science Center Foundation. Toyota organized a tweet drive during Endeavour's transport from LAX to the California Science Center, where twitter followers re-tweeted to raise $401,300. "Toyota has been a supporter and partner of the California Science Center from the very beginning," said Rouse. "We are honored to continue our partnership through this fun, interactive exhibit."
