What did you and your friends do this weekend? These guys successfully performed a 30-person backflip, on skis.

The world record attempt took place in Quebec, Canada. Check it out below (this was their second attempt):

According to the reddit poster, who says that they’re the second from the right in the video, they plan on getting Guinness involved:

“I wasn’t in charge of the whole thing, but I know that they want to try it again more officially next year. We were a bit last minute this year. But Guinness or not, I’m still pretty stoked about how well it worked!” they say.

World champion and future Olympic participant Mikael Kingsbury was a part of the jump, and tweeted about it:

We bet the world record !! 30 back flip hand in hand! Thanks to Mont St-Sauveur!
