Play That Carrot!

If you don’t love every vegetable out there, Junji Koyama might change your mind. In this video he drills right into a carrot to make a tube, then cuts a notch for the air to come through, and drills tiny holes to play notes. Wow, it’s a carrot flute! Junji also did this with other veggies to play Happy Birthday on each of them. It shows that we SHOULD play with our food.

Wee ones: In “Happy Birthday” Junji plays a carrot, broccoli, potato, and Japanese radish. How many veggies does he play?

Little kids: If Junji plays on his carrot the notes C, E, G, then back to C to repeat, what’s the 7th note he plays?  Bonus: What number note is the 3rd G?

Big kids: If 6 musicians each want 4 of his musical veggies, how many veggies does he have to carve?  Bonus: If the musicians eat 1/3 of their veggies before ever playing them, how many veggies are left to play?

The sky’s the limit: If Junji buys a total of 48 veggies, and there are 4 more broccoli stems than potatoes and 4 more carrots than broccoli stems, how many of each instrument will he have?

Wee ones: 4 veggies.

Little kids: C.  Bonus: The 9th, since it’s the end of the 3rd set of 3.

Big kids: 24 veggies.  Bonus: 16 vegetables, since they ate 8.

The sky’s the limit: 12 potatoes, 16 broccoli and 20 carrots. The mental-math shortcut is that if there are 4 fewer potatoes than broccoli and 4 more carrots than broccoli, that’s the same total as equal numbers of all 3 veggies, which would be 16 of each. That gives us 16 broccoli as before. plus 4 fewer potatoes (12 total) and 4 more carrots (20 total).
