I have got a spinning top from a Canadian manufacturer, and I am deeply amazed by how neatly it spins.
My interest in physics has led me to try to find out at what top speed I can spin the top and how that compares to other tops made from other materials and other shapes.
I have glued a little sticker to it and recorded it with my phone's camera but the frame rate is far too slow to be able to count the number of rotations over time.
I don't have access to specialized equipment but I can measure or approximate the volume, mass, density, temperature and probably also the moment of inertia. How do I measure the angular speed of the top?
