This is my second dexterity puzzle project with a little trick. They sell spice shakers as a couple for salt and pepper and I decided to make this puzzle for the second jar. This time in the jar, there are only a cube and a ball. On the cube there is a hole that the ball can enter inside it. This puzzle has a shorter acrylic pipe. But on the pipe of this puzzle there is a hole shaped like a key hole.
