The Mindcrack Party took place the night before the first day of Minecon 2013, and this is Basket's video from it. It runs a minute and a half: clips from the party set to music, with no talking until the very end.
At the party
The party fills a bowling alley. Scoreboards hang over the lanes, a "Bowling Check-in" sign hangs near the front, arcade machines glow along one wall, and a giant pixel-art Minecraft head stands in the middle of the crowd. The camera works its way through a packed room while people talk and take photos, and white captions name the YouTubers as they pass through the shot.
The second half is a run of quick photos of Basket posing with one fellow YouTuber after another, each labeled on screen.
It ends with a shout-out. Someone leans in close to the camera and says, "Hi, Chels, Chels, I did it! Hi, Chels!" and laughs. A card follows: "Stay tuned for more Minecon videos."
Hi Chels
"Hi Chels" is a separate clip, four seconds long, from the same party: someone in the crowd grins into the camera, waves, and says hi to Chels.
