CHALLENGING THIS WORLD RECORD

YOU NEED TO BEAT

01:25.09 min/sec

Rules

Use the official NoBook Lab (NB Lab) virtual chemistry app
Start the stopwatch on an empty workbench; apparatus and reagents may only be added after it starts, and saved setups or ready-made templates may not be used
Oxygen may be produced by any reaction in the app, but an oxygen storage bag or any other ready-made oxygen source may not be used directly
Collect the oxygen in one large test tube, with the Amount of Substance display switched on so the tube's contents show on screen
Stop the stopwatch only when the large test tube is free of tubing, droppers and all other apparatus, closed by its rubber stopper alone
After the stopwatch stops, the tube's display must show oxygen as the only gas for at least 1 second
Time runs from the stopwatch start to its stop, read to the hundredth of a second on camera
Must be one continuous, unedited video showing the device screen and a running stopwatch from the empty workbench to the stop
Must provide video evidence
