Put items on a scale and take them off

Place an item on a scale, wait for the reading, then take it off again. One round per clip.

Start: An empty scale showing zero and one item next to it.

Record: Place the item in the middle of the scale, take your hands away and wait for the number to settle. Then take the item off.

Done when: The scale is empty again and the item is back next to it.

Also counts: Kitchen, postal or luggage scales; food, parcels, bottles or tools; a bowl on the scale. Send as many clips as you like, changing the item 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.
