A Google-a-Day Puzzle for Tuesday, October 4th

Geek Culture

As we’ve reported before, our good friends over at Google are starting up a daily puzzle challenge. Each day’s puzzle will task your googling skills a little more, leading you to Google mastery. And much to our enjoyment, they’ve decided to share the puzzles with us at GeekDad (hmm… Google a Day? GD? GeekDad?), so each morning at 12:01am ET you’ll see a new puzzle, and the previous day’s answer (in invisitext) posted here. SPOILER WARNING: As a test, we’re going to 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:

If you draw a line between the capitals of the last two world countries (alphabetically by name), you can find a UNESCO World Heritage waterfall equidistant to the southwest. What is the name of the waterfall?


Search [detonation] to find that it involves a supersonic exothermic front. Search [define:supersonic] to learn that it is the rate of travel that exceeds the speed of sound. Search [deflagration] to learn that it involves subsonic combustion. Search [define:subsonic] to learn that it refers to travel that is slower than the speed of sound. The correct answer is detonation.
