PacSci-Doku: "Perpetual Flight"
By Dennis Schatz - Senior Advisor
Looking for the "Secret Messages" edition?
Do you Sudoku? It's one of the hottest number games around! Well, here's a twist we think you'll love. We call it PacSci-Doku, can you guess why? Here's how it works. Instead of filling in the blanks with numbers, use letters. Hidden in one of the columns or rows is the answer to a science question. The question in this edition is:
What airplane is designed to fly indefinitely without refueling?
To find the answer, complete this PacSci-Doku using the following nine letters:
U E I S _ P L M 2
Each row and column in the grid below has to have only one of each of these letters. Each of the 3 x 3 mini-squares in the 9 x 9 square also needs to have only one of each letter.
