Are you smarter than a 6th grader

Here is your free Friday fact. Actually, it's a question.

What is the largest volcano...in our entire solar system?

(dee, dee, dee, dee.....dee, dee, dee......dee, dee, dee, dee, DEE....dee, dee, dee, dee, dee---jeopardy music)

The answer is: Olympus Mons (oh lim' pus mahns). It is found on Mars. There is evidence that some of the volcanoes are active on Mars, but no one has seen a Martian volcano erupt. (Wonder what would come out of it, if it did erupt?)
Here are pictures of Bubble's model of the volcano.
Although she's done this "trick" a thousand times, she did it again for Prez.
Oooooo, aaaaahhhhhh!
Prez had his turn too and it just never seemed to get old. I had to ration my baking soda and vinegar.

Now, go impress everyone with your factoid of the day! (If you happen to win any game shows on this little piece of information, I will be looking for my small share in the winnings.)
