Change a roll or refill a dispenser

Fit a roll onto its holder, then take it off again. One round per clip.

Start: An empty roll holder and a roll next to it, both in view.

Record: Fit the roll onto the holder and let go for a second. Then take it off and put it back where it was.

Done when: The holder is empty again and the roll is back where it started.

Also counts: Toilet paper or paper towel rolls; spring-loaded, open-arm or standing holders; a tape roll on a dispenser. Send as many clips as you like, changing the roll or the holder 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.
