Google detailed its Expeditions project back at I/O, and now the company is looking to get schools more involved. To do just that, Mountain View will offer schools the VR field trip kits for free. The New York Times reports that Google is handing out the Expeditions package at no cost to help push the effort ahead. Each kit contains Cardboard VR headsets and ASUS phones for the students alongside an app for teachers that controls the virtual trips. And as you might expect, they're able to pause the action to ask questions as needed. Google isn't ruling out charging for the gear at some point, though, if it's able to make the price affordable enough for educators.
