What is a hobby nobody else has done that you want to start?
This seems like an odd question I know but I have been thinking there are probably so many theoretical hobbies that nobody has actually done before.
From the science fiction novel "The Syndic."
Polo, except with jeeps firing .50 caliber machine guns. You have a metal ball about the size of a truck tire and a field about 2 miles long.
That sounds... terrifying. I'm not sure I could even spectate.
More like really niche "sub-hobby" of homebrewing.
Growing/propagating your own yeasts. I did it about year ago and didn't have a time to get in to it again.
Closest thing I have ever done to that is Brewing Kombucha.
It is more sterile and intentional proces. But yeah at the end you end up with petri dish or tube with little dots that make beer/wine/kombucha or something else.
Sound a pebble dropping in water Splashh...
So like skipping a pebble across water but without having to worry about damaging coral or sea life because you can drop it in a safe area instead of the rock landing someone where further out in the lake or pond potentially hurting any ducks/water birds. It also has a lower skill requirement so that is a bonus.
Deep water version of your every day metal detecting. I know some companies already do salvage reclamation/research, but I'm talking about going hunting for smaller trinkets and seemingly "worthless" items in the eyes of corporations and research centers.
Only thing stopping me is I really don't want to be Oceangate 2 lol.
