This, as is the case with most Rube Goldberg Machines, is not the most efficient way to go about completing the task at hand. It is more entertaining though than the typical method, stoned or not.
From the YouTube description:
This is one of the Best Rube Goldbergs ever made, because it is more than a Rube Goldberg, it is a cartoon, collage and work of art, From Wobbly A Productions. This was made by Mr. Psychor a character played by Donald Drake. Mr. Psychor is an Acid Riddled Loon with Lame Scary Super Powers. Prepare yourself to induce craziness. High Doses, for this one baby! Still gentle though.
