CHALLENGING THIS WORLD RECORD

Plan your attempt.

Before you turn on your camera, take some time to think about the world record you are about to set. Will you do it alone, or involve your friends? Do you have all the props you'll need? Have you read the rules?
Film with purpose.

You don't need special equipment or a Hollywood director to document a great record. Focus on telling a great story. Aim to make your video entertaining and concise — rambling intros will scare away viewers. IMPORTANT: If you shoot with your phone, be sure to hold it horizontally.

YOU NEED TO BEAT

1.43 moles

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
Sodium chloride may be made by any reaction in the app, but the sodium chloride reagent bottle or any other ready-made sodium chloride may not be used directly
Collect the sodium chloride in one container, with the Amount of Substance display switched on so the container's contents show on screen
The container may hold no liquids or semi-liquids, since sodium chloride would dissolve, and no more than five substances other than sodium chloride; any gases and other solids are allowed within that limit
The result is the amount of sodium chloride, in moles, on the container's display when the stopwatch reaches 3:00, and the display must still show that amount afterward
Must be one continuous, unedited video showing the device screen and a running stopwatch from the empty workbench past the three-minute mark
Must provide video evidence
