What’s powering a Lightsaber? Apparently a crappy AA Duracell battery. And if you’re wondering, the tag at the bottom reads “Energy that lasts.”

No, I’m pretty sure lightsabers are powered by power cells… Geek creed, revoked.

Luckily, the ad isn’t real (I think) as it was created by a student in an advertisement school in Brazil.
