# Meet Chelsea, the Adorable Winner of our Communiversity Guessing Contest

This is Chelsea. She is 7 years old. And she is a Jolly Rancher counting genius.

This year for Communiversity, we hosted a guessing contest. Caroline graciously allowed us to borrow one of her large vases, and we filled it up with Jolly Ranchers. A lot of them.

The prize for the closest guess? A Chromebook, or even more exciting, a free month of tutoring!

The weather was chilly that day, but our booth was hot, hot, hot. We received over 700 submissions!

Can you guess how many Jolly Ranchers were in that vase? Scroll to the bottom for the answer.

## An Exclusive Interview

Princeton Tutoring: So I see that you chose the Chromebook as your prize. Do you think that when you go home you’ll come to your senses and regret not signing up for tutoring sessions instead?

Chelsea: I don’t think so.

Princeton Tutoring: What do you plan on doing with your shiny new Chromebook?

Chelsea: Actually, I’m not really sure what it is yet.

Princeton Tutoring: I think you’ll figure it out. Everybody is dying to know – what was your secret? You beat out math PhDs, engineers, and former guessing game champions. Which method did you choose to calculate the number of Jolly Ranchers? The vase wasn’t a perfect cone or a perfect cylinder. How did you modify the volume formulas, and how did you account for the additional volume taken up by the wrappers and air?

Chelsea: I don’t know. I just guessed!!

Princeton Tutoring: That sounds reasonable. Thanks for your time today, Chelsea, and please remember to use your guessing powers for good, not evil.

Chelsea: Okay.
