I know I am a few years late to this trend, but I did that thing that used to be huge on the internet and took a hammer to a bunch of aluminum foil and it actually worked! I thought it would be terrible, because every guide I found eventually suggested that you bring out your belt grinder and a bottle of aluminum polish, and I am not a metal worker, so I don't have that. Turns out you can get a very satisfying ball of aluminum with just the foil, a hammer, any kind of flat surface to work on and some toilet paper for polishing.
It's shiny and I made it and I can use it as a stress ball by just tossing it from one hand to the other and feeling the satisfying weight. I love it!
I want to touch it and rub it and this just looks like heaven for all my sensory needs.
Touching and rubbing my ball is pretty nice. You could make your own!
