Press buttons and flip switches

Press a button or flip a switch on, then off again. One round per clip.

Start: A button or switch and the thing it controls, both in view.

Record: Press or flip it once and take your hand away so the result shows. Then press or flip it back.

Done when: Everything is back as it was at the start: the light, the display or the switch.

Also counts: Light switches, power strips, kettles, microwaves, remotes, keyboards, doorbells or elevator buttons. Send as many clips as you like, changing the button or switch 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.
