Turn knobs and dials

Turn a knob or dial to a chosen position, then turn it back. One round per clip.

Start: A knob or dial with visible positions or marks, in view.

Record: Point at the position you will turn it to. Turn the knob there and let go for a second. Then turn it back to where it started.

Done when: The knob is back at its starting position.

Also counts: Stove, oven, washing machine or heater knobs, volume dials, timers, taps or thermostat dials. Please do not light a gas burner. Send as many clips as you like, changing the knob or the position 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.
