Anybody used to speedstack?

When I was younger, my parents bought me a stack of speedstacking cups for Christmas.
I used to use those all the time
I just recently tried to do it and I honestly can’t do it anymore

I was wondering if anyone here has ever done speedstacking or is still doing it?

I used to do it as demos at a toy store I worked out; I wasn’t great guy it was pretty fun

I used to a few years ago. I did it all the time, every single day. I loved it, and then one day, I just stopped. I dug it out of my closet not long ago actually, but I’ve lost what little skills I had. I think I’m going to try and pick it back up though. Maybe one day over the summer when I’m really bored…
