Ethan Brown is only 12, but his ability to do tricks using mental math is incredible.
At last week’s Skepticamp in New Hampshire, Ethan created a 4 x 4 magic square after audience members filled in some of the boxes for him at random. And he even found a way to get the columns and rows to add up to an appropriate number for that particular audience 🙂
…. and I’m jealous. I want his skillz.
Ethan, when you come to Chicago next month, you have an open invitation to perform in front of all my classes 🙂
