For those of us that saw footage of the drunken Darth Vader attack and found ourselves slightly disappointed by the… well… un-Star Wars-like nature of the Sith Lord’s weapon, Instructables has a DIY kit to ensure that our next drunken rampage is truly worthy of the Dark Side.

The project, from Instructables user Ricardoaraujo, uses a normal toy lightsaber hilt, some AA batteries, a rubber hose and a couple of LEDs to build a weapon you’d be proud to kick Jedi arse with. Now all you need to do is knock back a couple too many Guinnesses and find some Obi Wan Kenobi-worshipping dork to smack around. Death by pretend lightsaber it shall be!
