<!-- .vabout -->
This is a sentence of the lesson «Floating in the real world: ice, submarines and balloons» of the physics course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (waxy feet, drop, resting paper clip, pond skater), what happens, when and where, as Mova's frames read it from the tree.
