This is for real.  This guy carries out a dangerous laser experiment form home.  This looks like a thin jedi green lightsaber except it extends a looooot longer.  Apparently the narrator starts by lighting a firecracker with this thing.  And the fuse of course gets lit and pops.  Beavis and Butthead would be drooling at this video.  NEVER do this yourself it is extremely dangerous.  This particular post is just coolness.  There isn’t a scientific paper being researched or a topic debated.  It’s just fun to watch!

See what this handheld “lightsaber” looks like on video on the next page..
