Moving the juice pouch off screen should void the attempt. While not directly stated in the rules, it would fall into the category of not enough information to verify.

Sorry to nitpick, but neither Kyle nor Colt pulled the straw out when they were done. With the straw still in it, nothing should come out. Colt even puts it back in his mouth after he was done.
I don't question their times, but they should be following all of the stated rules.
This is breakable, just very difficult. I have stacked two pennies on their sides before, years ago. There are also videos on youtube with various different coins doing the same thing.
