Hello! Welcome to this week’s edition of “Things You Really Probably Shouldn’t Do At Home! Seriously.”

Armed with a pinch of ingenuity and a heaping fistful of insanity, garage inventor Colin Furze has recreated Wolverine’s signature claws. They extend! They retract! They… look incredibly dangerous!

Others have taken a stab at this sort of project before, but all of those I’ve seen only do one half of the equation: the claw extension. Once the claws came out, they had to be manually set back in place. Weaaaak.

With the help of a super clever compressed air system, Furze’s claws are able to extend and retract on command. Sure, he needs to wear a big ol’ backpack to make it all work — but besides swappin’ out your skeleton for one with a bit more adamantium, this is probably about as close as you can get to the real deal.

As much as I’d love to play with a pair of these, I’m pretty sure I’d end up stabbing myself just putting on the backpack.

If the guy in the video looks familiar, don’t be too surprised. This isn’t Furze’s first venture into the land of insane DIY. Back in 2007, he made a massive (and terrifyingly shoddy looking) “Wall Of Death” so he could ride around almost horizontally on his lil’ Honda Skyride.

In 2012, he modified a mobility scooter, originally meant to go about 4 MPH, to blast around at just past 70.

Furze is promising more X-Men themed projects in the coming days (presumably thanks to the upcoming opening of the new X-Men flick, Days Of Future Past), so we’ll keep an eye out for more absurdity.
