Riddle: What kind of music can you hear in space?
Answer: A nept-tune. It’s a pun that combines “Neptune,” the planet, with “tune,” a piece of music. The riddle asks what kind of music you can hear in space, and the answer plays on the pronunciation “Nept-tune,” sounding like “Neptune.” So the “music” in space is a “tune” from “Neptune.” It’s just wordplay—no actual sound involved.

Riddle: How do you spell hard water with three letters?
Riddle: I am seen in the water and seen in the sky, I am in the rainbow, a jay's feather, and lapis lazuli. What am I?
Answer: The color blue.  Why each clue points to blue:
  • Water: Large bodies of water often look blue because they reflect the color of the sky and, to a lesser extent, water weakly absorbs longer wavelengths (reds) more than shorter ones (blues), leaving a bluish appearance.
  • Sky: The sky appears blue due to Rayleigh scattering—shorter blue wavelengths of sunlight scatter more in the atmosphere, making the dome of the sky look blue. Rainbow: Blue is one of the visible color bands in a rainbow, between green and indigo.
  • Jay’s feather: Many blue jays look blue not from pigment but from structural coloration—the microscopic structure of the feathers scatters light to produce blue. 
  • Lapis lazuli: This gemstone is famously deep blue because of the mineral lazurite.

Number Of Chairs

ROD: 11-21-2025

Riddle: What's the least number of chairs you would need around a table to sit four fathers, two grandfathers, and four sons?
Answer: Four. The trick is that the roles overlap. You only need four chairs because the same four people can simultaneously satisfy “four fathers,” “two grandfathers,” and “four sons.” A classic arrangement is: great‑grandfather, grandfather, father, and son. In this setup: The great‑grandfather and the grandfather are both grandfathers. All four can be fathers (the son can have a child not present). All four are also sons of someone. So the least number of chairs is four

The Holes

ROD: 11-20-2025

Riddle: A hole leading in, a hole leading out, we connect to a cavern that is slimy all throughout. What are we?
Answer: It’s the nostrils—the nose. The “hole leading in” and “hole leading out” are the two nostrils, which open into the nasal cavity. That “cavern” is the mucus-lined nasal passages, which stay moist and slimy to filter and humidify air. The riddle’s accepted answer is “a nose.”
