Twenty ants are hidden across Hampstead Heath. No map. No coordinates. Only warmer or colder. Find one, keep it.
Best on foot, outdoors, with location on.
Headphones make it easier.
Each one is somewhere on the Heath. You will not know its number until you find it.
This ant has settled here for you. Lift it gently and take it home.
Private. For planting and testing. Coordinates here are local to this phone until they move into the live store.
Uses your current location to scatter four test ants at increasing distances, so you can walk the mechanic right now.
