This scene follows raw propolis ("bee glue") through a real production line: bees seal a plastic trap grid laid over the top bars of the hive, the loaded trap is frozen until the resin turns brittle, it is flexed to crack the propolis into granules, and those granules are macerated in ethanol until the resins dissolve into a standardised tincture, leaving insoluble wax behind as sediment.
A well-designed plastic trap can yield 30–60g of raw propolis per hive per season — and because bees produce it defensively rather than as a harvestable surplus like honey, per-gram prices for cleaned propolis and its tinctures are often far higher than for honey.
A three-stage 3D production line — a plastic trap sealed by bees, a freezer that cracks the trap into granules, and an ethanol jar that macerates those granules into a standardised propolis tincture.
Trap slot width drives how fast bees seal the trap, freezer temperature sets granule purity, and ethanol strength plus maceration time (with optional daily agitation) determine how much resin dissolves versus how much insoluble wax settles out as sediment.
Adjust the trap gap, freezer temperature, ethanol percentage and maceration days, and toggle agitation. Watch propolis accumulate on the trap, granules crack into the tray, and the jar's tincture darken as resin dissolves and wax sediment settles.
Because bees produce propolis defensively rather than as a harvestable surplus, cleaned propolis and its tinctures often command a far higher price per gram than honey from the same colonies.
