I checked one of my old math books (for about $5$ years ago) and one of the problems is as follow:
$a)$ Why compass draw a circle?
$b)$ Can you give an example of an instrument to make sphere in space ?
Part $(a)$ is easy to answer. but I'm eager about knowing the answer of second part. I searched on internet but couldn't find such instrument.
Rotating a circle around its diameter produces a sphere.
If they want a physical device, a gyroscope can be pointed in any direction and spins. An ice cream scoop carves out parts of a sphere.
Not sure what else they might be asking for. It's not as if we have a 3d piece of paper to draw on.
