$10 Lightsaber Vs. $400 Lightsaber
“Star Wars” fans would recognize either of these items as a lightsaber—a weapon used by the Jedis, the Siths, and Darth Vader in the sci-fi film series. But the one on the left is $10 and is so dim compared to the one on the right, which is worth $400 and lights up spectacularly. It even makes the swooshing sound when the user moves the sword back and forth.
