Dogs: Don’t Try This at Home

April 9, 2017

Usually when a balloon pops, we’re a bit shocked, then sad. But here’s someone who pops balloons on purpose – and she’s a dog. Anastasia, a Jack Russell Terrier, can pop 100 balloons in less than a minute. She set a record in 2008 on live TV, finishing in 44.49 seconds . How did she do it? She zigzagged through the pile and popped the balloons in rows. She doesn’t hold the world record any more, though: in 2014 her daughter Twinkie popped 100 balloons in 39 seconds!

Wee ones: How many colors of balloons can you count in the picture? Count as many as you can!

Little kids: After Anastasia pops the first 7 balloons, what number balloon comes next? Bonus: If Twinkie pops 4 more balloons than you do, and together you pop 10, how many do you each pop?

Big kids: Once there was just 1 balloon left out of 100, how many balloons were popped? Bonus: Anastasia runs 4 laps to pop the 100 balloons. If she popped the same number on each time lap, how many would she pop on each trip?

The sky’s the limit: If they lined up 169 balloons in a perfect square, with the same number of rows across as front to back, how many balloons wide would that square be?

 

 

Answers:
Wee ones: We count 8: red, pink, purple, blue, green, yellow, blue-green, and peach.

Little kids: The 8th. Bonus: You pop 3, and Twinkie pops 7. If you’d popped the same, you’d each pop 5. For each balloon you let her pop, you pop 1 less than before, separating you by 2 total. So you come down 2 balloons from the middle to have a difference of 4.

Big kids: 99 balloons. Bonus: 25 balloons.

The sky’s the limit: 13 balloons wide. This takes some clever guessing. The answer has to be more than 10, and fewer than 20 (20 x 20 = 400). And it has to end in either 3 or 7, to multiply by itself and make a number ending in 9. So you try 13 x 13 and 17 x 17. 13 is the winner.
