I See London
Another kid-ism from my son:
Well, it has some of the right components.
"London, London, I see your underwear!"
Well, it has some of the right components.

Pendulum Waves
Original Link to Maker Blog
Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and (seemingly) random motion.
The period of one complete cycle of the dance is 60 seconds. The length of the longest pendulum has been adjusted so that it executes 51 oscillations in this 60 second period. The length of each successive shorter pendulum is carefully adjusted so that it executes one additional oscillation in this period. Thus, the 15th pendulum (shortest) undergoes 65 oscillations.

Outside the Box
My six year old son had a word problem in his homework: "Ashley drew a square on her paper. How many sides does it have?"His answered, "2."
My wife questioned him to give him another chance. He must remember how many sides a square has.
But he insisted, "Paper has two sides!"
Good boy.
