Styrofoam Cup Woman

Can make styrofoam cups out of thin air, but they always have a quarter-sized hole at the bottom.

PopcornHand
If you hold corn, it will chsnge into popcorn.

Roof Climbing
Wall climbing but just on roofs. You're basically just walking on roofs. You're not Spiderman, you're not special, anyone can walk on roofs, but your Super Special Classified Power is Climbing on Roofs. (I bet Violet Sorrengail and everyone in Fourth Wing would've loved that for the parapets, but that's basically the only use. Unless you're a construction worker or something.)

Carpet-Straighter
You can straighten a carpet after it was rolled for too long.

the superpower to change the colour of the whites of your eyes. But pink yellow and green only.

The ability to test for an electricity with your two fingers, but you are not immune to electrocution.

you can take a sickness from anyone and give it to yourself, but you have an immune disorder.

Ability to always guess which time it is in middle of Pacific

the ability to sneeze and turn back time, but it only works when you're seasonal allergies are acting up

The ability to see the future but it's only what movie you're going to watch tomorrow.

my dad suggested this one:

the ability to create traffic cones. also whenever i bring up this discussion he always argues that there's no truly useless superpower,, maybe he's kinda right lol
