Copa, if they’re into gardening or cooking at all, I think a small aerogarden with cherry tomato and jalepeno or herb pods would be pretty fun. They’re not a lot of work after the initial set up – just water as it indicated and add a bit of plant food when the light goes off (it’s included in the pod kits) and it’s fun to watch them grow – bonus points if you can eat what you grow.
An aunt one year ages ago gave me a potted lime tree and that was fun, too. It was harder to work with, though, and needed a lot of babying to get good limes.
If anyone is a Swiftie, a Kelce jersey might be fun. But useless they break up in a month or two.
If you have any readers, maybe a kindle gift card or subscription or something similar so they can buy books?
Something along those lines for gamers? (I literally know nothing about gaming. Haven’t touched a video game since the OG Nintendo days.)
