Appreciation post: watched a freshman turn 6 stacked trays into a bridge that held 14 lunch boxes
Two months back this kid was just sliding trays around, and now he's interlocking the rims so the whole thing locks flat and stiff. Last Friday he spanned two tables with 6 trays in front of about 20 people at Lincoln Middle and didn't even brag about it. What's the best tray build you've seen somebody figure out on their own?
