Seed Dispersal Engineers

Collect five seeds. Work out how each one moves. Then design a better one and test it off a balcony.

Wind seeds are the easy ones and children copy the helicopter shape immediately. The interesting designs come from children who try to improve on hooks or on floating.

Testing is a drop from a height with a timer. Longest airtime wins.

The page has the collection frame, the dispersal categories, a design space and a results table. It also asks what the seed's actual job is, because a design that stays airborne for ever and never lands has failed at the thing it exists for. That point takes a while to land and is worth waiting for.
