Zip and unzip a bag or jacket

Zip a zipper closed, then unzip it again. One round per clip.

Start: A bag or jacket with its zipper fully open, in view.

Record: Zip it closed all the way (on a jacket, join the two ends first) and let go for a second. Then unzip it all the way.

Done when: The zipper is fully open again.

Also counts: Jackets, hoodies, backpacks, pencil cases, pouches or suitcases; metal or plastic zippers; lying on a table or worn. 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.
