The person must be at least 1.82 meters tall. Preferably, their hands should be like those of a volleyball player, large. The house should have a corridor suitable for running and gaining speed. The house must receive an excellent amount of sunlight from the south between 3:30 PM and 4:00 PM. The walls should be painted with non-staining, preferably acrylic paint, and the flexibility of the space is absolutely necessary. The room must also contain 2 kilos of strawberries and pastry cream. A mirror in the room is a must. What makes the Oslo dunk perfect is that the mirror is hung on the wall where the sun hits, exactly equidistant from the ceiling and floor. If the mirror is hanging from the ceiling, one must immediately abandon the dunk.
