How to launch a lab
- On a computer: use Chrome, Edge or Safari. Press Play, and the lab opens over this page. Give it a few seconds to load the first time, then click through each step. Press Close to come back.
- On a tablet or phone: the lab switches to touch controls automatically. A tablet gives the best experience; on a phone, turn your screen sideways.
- On a Meta Quest headset: open this page in the Quest browser and press Play. Inside the lab, choose Open in VR, then Enter VR. You can use the controllers or your hands.
If a lab doesn’t load, refresh the page or try another browser. Older phones may run the labs slowly.
