One window (barred, let's make these bars nearly invincible), locked and reinforced door. A box, a lightbulb, dust, belly button lint, a spoon, duct tape, rope, a pipe, hacksaw, a few springs, screws, and a metal chain, plus your brain. Food comes from a hole that appears from the floor every noon, sharp. Water comes from a gutter leading from the roof through the window. You can only work for 1h at a time, they watch you. How do you escape? [spoiler]Anything is possible[/spoiler][spoiler]Removed table and chair, lol, everyone says same answer[/spoiler]
