There's a good chance that at some point you've seen Jimmy Fallon playing Flip Cup with one of his guests. The game involves drinking from a cup and then trying to flip the cup over completely on a table. That can be pretty challenging, depending on what it is you're drinking.
It's already a pretty great party activity for when beer pong starts to get boring, but last night on The Tonight Show, Jimmy and his celebrity guest Liam Hemsworth put a refreshing summer spin on the tradition in a new game called Slip and Flip.
The premise is basically the same as Flip Cup, except in this version, the competitors are required to slide back and forth on a wet mat to get to the cups, which are set up at both ends.
As you can see, Jimmy and Liam were in it to win it.
This gives us an exciting new idea for our next barbecue. If you have enough space for it, it looks like the perfect way to cool down on a hot summer day. You probably won't be able to get Liam Hemsworth to join you, though, so your friends and family will have to do.
