@ortwin: Quite sure he's filthy rich, but more to the point, listen to his huge hit "Margaritaville". He eventually made a career out of being a Carribean island boozer/stoner.
Looked at the video, looked up the lyrics, still I don't get it. Must be something I can't pick up having a different mother tongue and somewhat different cultural background.
The word "pop
top" appears in the lyrics, I thought that might be something related to spinning. An image search for it brought this up:
So maybe not...
But do you remember how we could get that ring spinning and flying by using that springy part as a starter? Almost like the wind up starter I showed recently. Couldn't find a video on YouTube of what I mean. Much less an old school can lid to give you the performance.
Actually the trick won't work with the first lid shown here, that little groove encircled in the second picture is essential.
