While logging in some pool time during the family trip to Thailand, Brandon Jenner comes up with a cool idea for a video trick with his sisters in this deleted scene from Sunday's episode!
"One of you should get the water real calm and then duck down," their older brother instructs them. "And then right when you duck down it's the other sister!"
Brody Jenner watches with amusement as his sisters attempt to do the trick, which is a lot harder than it looks!
Kylie tries it out but gets it wrong, so Brody, in true older brother fashion, tries to help her out by offering some helpful tips.
Watch the clip above to see if the two have what it takes to pull off the ultimate pool trick and tune-in on Sunday to see part three of the Kardashian vacation in Thailand!
