I do not know its name nor who makes it. It is also hard to describe but here goes: It is a clear box about (1.5")^3. Inside are three (3/4) yellow planes which intersect in the center of the box and extend to the sides. ____ | x | | ----- | 0 | |_______| Here is a picture of the 3/4 plane. The "x" and "0" are holes which will be explained. The box contains three identical blue objects which look like half dumbbells. They will fit through the "0" hole but only the shaft will fit into the "x" hole. The puzzle is to insert each of the three shafts into each of the three "x" holes. It is easy to get one in and I once got two in. But to get all three in simultaneously seems impossible. Does anyone know whether this puzzle can be solved and add more info on who makes it, etc?
