Size

Not sure how relevant the size is. Of course the ratio gravity force/friction is important, so the range of sizes which exhibit spin reversion will depend on the material but especially of the surface roughness (which depends more on surface treatment than on material) of both the rattleback and the support on which it is spun. --Josce 14:35, 14 December 2006 (UTC)[reply]
