History
A Columbus Egg puzzle using a rolling ball was described in a 1893 book. The Montgomery Ward catalog of 1894 includes a "Columbus Egg" toy.
There are at least 18 United States patents for such devices, starting from 1891.
The German company Pussycat (toy manufacturer) sells a Columbus Egg that can be balanced by holding it upright for 25 seconds, then quickly inverting it. The egg will then stand on its pointed end for 15 seconds, then topple on its side.
