Build and flatten a cardboard box

Fold a flat cardboard box into shape, then flatten it again. One round per clip.

Start: A flat, folded cardboard box on a table or the floor.

Record: Open it into shape, fold the bottom flaps closed and stand it upright for a second. Then open the flaps and fold it flat.

Done when: The box lies flat again.

Also counts: Shipping boxes, shoe boxes, gift boxes or pizza boxes; any size; flaps that tuck in or just fold. Send as many clips as you like, changing the box each time.

How: phone on your head (not on your chest or in your hand), both hands free and in view the whole time, good light. One continuous clip of one complete round, about 10-60 sec (max 90 sec). Start recording a few seconds before you begin and stop a few seconds after you finish. Keep the app open until it uploads. Keep faces and documents out of view.

Can be declined if: not first-person, phone held in a hand, hands out of view, the start or the result not visible, the round not finished, or too dark or blurry.
