Wondering about wonders of the world?

I just discovered this site and signed up for the emails but I think it would be a fun morning activity for students in a class or for a family. The site is called Wonderopolis: where the wonders of learning never cease. Here is the link: Wonderopolis
The site is split into wonder of the day, explore wonders and what are you wondering? Wonder of the day features one wonder or question of the day such as who created escalators, why do you need your toes and my favorite, who invented candy bars.  On the page claaed explore wonders, you can search through wonders and they have a filter system where you can search by grade or subject matter. As you wondered, What are you wondering section allows you to pose a question or a wonder by email. You can also sign up to get a wonder of the day email. For those trivia lovers out there, this is for you!
