Creative Project😅

Er

So I know this app is for periods but all you ladies are so creative and I need help😂 I’m doing a project for Economics and I have to come up with a product to appeal to 17-19 year olds. It can be as real or as fake as you want! What sort of product would appeal to all people this age? I’ve gone from High School Tinder to An All Healing Medication, but I haven’t quite found one I really like.
