You guys could have washed the dishes, gone and got a plunger and unclogged the toilet, and then drank a beer in the same amount of time. Lol looked fun though.
I highly recommend you watch RU-vid user AVE's video on his Plinko, it seems these guys are either ripping off the idea or are just making their own. But I think AVE was the first to build it or at least put out a video. His is also way cooler and involves electronics. His commentary is also hilarious, (especially if you are Canadian!)
