Within her brick-built lab, the LEGO designer is trying to synthesise a new batch of green-polyethylene from the sugarcane she has grown hydroponically. But alas! She hasn’t noticed that the first batch has spilled on the floor, and her lab has started sprouting with plastic plants!

For those chemists out there, see if you can spot the formula for polyethylene hiding in the build!
