What do you do while watching something?

I can't sit still while watching stuff so I usually fidget or eat or do something on my phone to do something and not just watch. I can't just watch something unless it's a horror movie or something really really interesting. I tried fidget cubes but I keep losing them and also they're not as fun(?) and I tried doing hobbies like crocheting but I need more attention on the crochet so I drift from the show's content.

Please let me know some good things to do while watching stuff!
