A light saber is a really cool weapon that you might have seen in Star Wars movies.
It looks like a sword, but instead of a metal blade, it has a beam of light.
It was first imagined by George Lucas, the maker of Star Wars, as the signature weapon of the Jedi warriors and their enemies, the Sith.
In the Star Wars stories, the light saber’s beam can cut, melt, and burn through most things it touches.
One special thing about light sabers is that their blades can clash with each other, unlike normal light which would pass through.
If you remember, Jedi knights use light sabers to block and deflect laser shots from the bad guys.
A light saber is made from a crystal that determines its color and even its sound.
Most Jedi light sabers are blue or green, but a few are purple.
And did I mention that the bad guys, the Sith, usually have red light sabers? So, don’t forget to choose your light saber color wisely when you become a Jedi.
