I tried to trick it with User Agent Switcher, but no go. It's not just examining the user agent -- it's looking for window.chrome, too.

Having watched the video and the word-spelling at the end, there's nothing about this sort of content that strikes me as stuff that can't be done in other browsers. And isn't that supposed to be the point of experiments like this?

Google should be showing us stuff that can't be done in any browser but Chrome because of those other browsers' technical limitations or deficiencies ... not just because they have the wrong user agent.
