small puzzle, ball in a cube

these are very simple and quick to make, makes a great little trinket to play with, yes even and adult, i was told that i should market them as the ADD solver lol, but there not my idea, ill give the link below on how they are made, but think about it before you look, how would you get a steel ball into a wooden cube so that it cant come out, the cube can not be cut in half

i made mine 3/4 in square with a .395 ball so i drilled .375 a 3/8 drill, i only did that cause im a machinist and we happened to have those ball bearing around the shop, i tryed making a couple that were 1/2 in cube but that is a lot harder because of the thinner wall, i was going to trim them down after but they look fine big, i started about 20 and ended up with about 15, MAKE SURE YOU WAIT AT LEAST 3 DAYS, i tryed 4 at 2 days and one worked, broke the other 3, then i waited till the wood sunk in the water, it was 4 days. i dont know what kind of wood that i used, you tell me? it was a bowl blank that was pretty soft, its the same wood that i used for the lids on my dovetail sliding boxes im going to add after this

still not sure on the wood, i dont even know if i would remember if someone said what it was, but thanks
