Click on the Demo button in the top-right of the homepage to view the Classroom-Demo mode.
Classroom-Demo mode is an Augmented Reality viewing-mode designed to allow students to view specific molecules in AR by pointing their camera a printed AR marker. As of September 2020, all models in the Classroom-Demo mode use the same printable marker, which is availble here: MolXR Augmented Reality Marker.
To change molecules simply click on the "Gear" icon at the top left side of the page and select a desired molecule from the drop-down listing.
Some ad-blocking browser extensions cause problems with AR, and do not allow molecules to load at all. If you're having trouble viewing molecules in AR using Classroom-Demo mode, try temporarily disabling any ad-blocking browser extensions for our domain. We don't serve ads anyway :)
