President Obama in Mythbusters Episode

The President made a guest appearance on the December 8 episode of Discovery Channel's "Mythbusters". More than 2 million people tuned in to show. 

The December 8 episode of Mythbusters was taped on July 27. The episode is called "Archimedes Solar Ray."

President Obama  challenged "Mythbusters" hosts Jamie Hyneman and Adam Savage "to revisit an ancient and somewhat-controversial myth: Did Greek scientist and polymath Archimedes set fire to an invading Roman fleet using only mirrors and the reflected rays of the sun?" in short asked the mythbusting duo to solve the legend of Archimedes' solar ray.

Discovery Channel's "MythBusters" is a reality series that sends adventure-seekers to discover the scientific truth behind famous urban legends.

President Obama was seen with hosts "MythBusters" hosts Jamie Hyneman and Adam Savage in a White House Science Fair where the President announced "I can announce today that I taped a special guest appearance for their show, although I didn't get blow anything up...I was a little frustrated about that."

The said myth was said to be already tested by the show twice in episodes in 2004 and 2006. A discovery channel representative said that "Regarding the Archimedes myth, fans are constantly asking the MythBusters to re-test it under different circumstances. Archimedes Solar Ray was ultimately chosen by the White House because it provided the greatest opportunity to get students involved in STEM [science, technology, engineering and math] in the most real way possible. We enlisted the help of 500 middle- and high school-aged students from Alameda, California, to help with the testing."
