President Barack Obama may be having difficulty raising his approval numbers, but can he get one of the world's biggest mysteries solved?

This week on Mythbusters, Obama will task hosts Adam Savage and Jamie Hyneman with re-testing the myth of Archimedes Solar Ray -- the supposed weapon that destroyed Roman ships around 200 B.C. by using only mirrors and the sun.

The episode will air Wednesday night at 9 P.M. on the Discovery Channel.
