This math vase of degree 3 is a classic from school teaching.
Indeed, it is just the graph of the function y=(x+9)*(x-68)*(x-68)*0.0003+10, rotated about the x-axis. Such math models are common examples for computing the area or the volume of a surface of revolution given by rotating a graph about an axis.

We also created a version of this vase with bottom which you may actually use to measure the amout of water that fits into it (although the “strong & flexible” material is not really watertight). Some more school math sculptures are listed below:
