With free time and some thought, everything becomes possible, a YouTuber who calls himself Kaplamino designs a set of labyrinths and complex paths calculated with impossible precision to move a small glass ball (blah) in a very fun scene.
This young man uses a table and a set of very simple tools to make those ingenious and pinball-like tracks, which end with the ball in the end inside a glass cup, on his channel you will find mazes of other types as well, and all of them need, as we said at the beginning, a vacuum and a lot of thinking.
