Leave it off for a few days and stick it near a dehumidifier if you have one. As long as it stays off until it’s completely dry it should be okay.
Agree with the other commenter that rice isn’t the best bet. Even if nothing ‘bad’ happens, it can get stuck in the heat sink and/or get moldy if you don’t get it all out.
If you’re really worried, you could take the shell off the deck off and dry the inside.
I enjoyed this, thanks for posting!
