I just had to laugh from some of the quotes in the article:

"A similar problem was experienced in the earlly seventies when Microwave ovens were launched that made farting noises. Sales did not take off until they were adapted to make the reassuring humming noise we are now used to."

And...

"these are serious pieces of technology that in the wrong hands could cause severe damage" said Sagaumuki and highlighted that 3 of his researchers had got carried away at a celebration party three weeks ago and two of them were hospitalised after re enacting the Darth Maul / Kenobi/ Gon Gin sequence from Phantom Menace.

My kids are dangerous with tree branches and cardboard paper towel tubes. I do not even want to think about them with a real light saber!

And if my wife ever got a hold of one... "Take out the trash - NOW!"
