I had the most fun trying out with a light and bouncy ball. Of course It didn’t knock down many pins. ^^ Neaither did the really heavy version, because it just stopped moving.
I tried to capture a video but realized I didn’t know at all what I was doing and couldn’t turn it off, so I only have an image to show.
I watched the lecture twice before to make sure I got everything before actually trying it out for myself.
