Glow in the dark, because I'll never be in the sun enough to charge it based on my experience with other glow in the dark products

If I had to pick I'd go glow in the dark. Imagine having to grow and shrink every time after getting in the shower. Hell, you might even have to wait awhile before your clothes fit.

How fast do you shrink back to normal? Is it like immediately once removed from water? Once you towel off? Or do you have to hang out in the sun for a bit. Could you keep the size going with like putting your hand in a bucket of water

#2 for sure, I've always wanted to be one of those spongy water bottle animals

Do the inside of my eyelids glow in the dark?

Square-cube law. Glow.

imagine just chilling out in the bath before your big Bumble date
