(Assuming the shower is running. Any temperature.)
The best I could come up with was a hot soup, but eventually you’ll get more water then broth. There has to be a better food out there for those hungry showers!
Something hot in an open bowl sounds like the worst food to eat in a shower TBH.
I’d go with something cold in a tube, like an ice pop. Or maybe a beer in one of those fancy insulated tumblers with a closeable lid.
I drink beers out of cans/bottles while showering regularly. The amount of water that gets into the can/bottle is neglible.
No glass bottles please. We don’t want you to star in any internet videos of horribly disfiguring home accidents, if you slip.
For fast eating challenge try cotton candy
Do this if you have ever wanted to identify with a raccoon.
