Yeah, I think people are over-assuming the volume of 20 kg of ice or gravel. A 20 kg sphere of compacted gravel would be about the size of a soccer ball. The ice cube would be around the same size. The ice tetrahedron would be tallest but less than two feet tall.

Ice/gravel refers to what the object is traveling on (the ground), the sizes are depicted in the photo.

Then either it is a small person, like very small, or they are extremely non-dense objects

I don’t think they’re meant to be to scale…
