Even if you don’t know what Tetris is (you don’t know what Tetris is?!), this video is still worth watching just because the guy in the back.
When I watch videos like this, I like to think about all the work that has gone into it. Like filling up the bottles with the right amount of water and putting them in the right position. Then learning to ‘play’ them at a decent speed.
I wish I had that much time on my hands.
And seriously, watch the guy in the back. I think he is the one having the most fun.
