english: So bees fly to some plants and they scrape these very, very sticky resins off the leaves, and they take them back to the nest where they cement them into the nest architecture where we call it propolis.
non_english: Včely letia k niektorým rastlinám a zoškrabujú túto veľmi, veľmi lepkavú živicu z listov, nesú ju naspäť do hniezda, kde ju zatmeľujú do architektúry hniezda a tam sa z nej stáva propolis.
