# Plop

## Equation

$x^2 + (z+y^2)^3$

## Properties:

• degree 6
• unbounded
• singular cusp curve, which is smooth

## Some story

I wish I understood why this surface makes a sound. I personally haven't dropped it in water or mud, but I bet it's not an especially pronounced plop.

Decomposed using a random projection, and a bounding sphere of radius 5.
