# Oil and water, and things that won't mix, sentence 1

<!-- .ven lang=en -->
Water molecules cling to each other far more than to oil, so they squeeze the oil out, and oil, being lighter for its size, floats.

<!-- .vintro -->
**Who acts:** Water molecules, molecules, oil · **What happens:** cling, squeeze out, be, float · **To what, where:** oil

<!-- .vabout -->
This is a sentence of the lesson «Oil and water, and things that won't mix» of the chemistry course of Mova's primary school.

**The tree:** Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R8-pos-agree ×2. **The frames** are read from the tree by Mova's frames reader (`prag`) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
