OP, at least you weren't in the bathtub when she threw it in! :-)

Good thing it wasn't plugged in at the time. Otherwise, you'd have to shop for a new sister, too.

Mm I would pay more attention to your sibling she might try to attempt suicide and got caught or you came home earlier or some other thing I'm telling you this cuz I used to try to kill my self and I was always waiting to be alone and one time I forgot some razors at the bath and my mom ask for them which I just say I was just trying to learn how to shave with them so I might be wrong but just keep an eye on them

Tell her to get in it with it

I hope your younger sister is under 5......

Let it dry out it will be fine.

A toaster isn't so expensive. It's more important you explain to your (hopefully very young) sister the dangers of putting electronics in water.

Yes, because "it looked dirty."

Kids just get more and more dumb.

Um how old is she? if over the age of say 3 I'd talk to my parents about her.
