When these small wooden tops are spun, they start precessing until the heavier hemispherical end is lifted, seemingly against gravity. The Nobel Museum in Stockholm reports that Neils Bohr was captivated by this top when first observed over fifty years ago. These newly designed tops, with a hollowed out sphere, are like the original and work extremely well! The natural wood ones can be decorated by students. 3.8 cm (1.5") tall, 3.2 cm (1.25") dia.
