Our good friends at Google run a daily puzzle challenge and asked us to help get them out to the geeky masses. Each day’s puzzle will task your googling skills a little more, leading you to Google mastery. Each morning at 12:01 a.m. Eastern time you’ll see a new puzzle, and the previous day’s answer (in invisitext) posted here.

SPOILER WARNING:
We leave the comments on so people can work together to find the answer. As such, if you want to figure it out all by yourself, DON’T READ THE COMMENTS!

Also, with the knowledge that because others may publish their answers before you do, if you want to be able to search for information without accidentally seeing the answer somewhere, you can use the Google-a-Day site’s search tool, which will automatically filter out published answers, to give you a spoiler-free experience.

And now, without further ado, we give you…

TODAY’S PUZZLE:

Consider the element that makes rubies red. What color does this element become when it’s added to beryl to create another precious gem?

YESTERDAY’S ANSWER (mouseover to see):

Search [deepest point undersea] to find that Earth’s deepest point is the Challenger Deep at around 36,000 feet. Estimates of depth vary from 35,813 feet to 36,168 feet. Search [highest point above sea level] to find Mt. Everest at 29,035 feet. Google the difference: [36,168 - 29,035] to find that the ocean’s deepest point is 7,133 feet deeper than Mt. Everest is tall.
