    You probably filled the spark plug holes with water.
    Did you use a pressure sprayer?
    You can pull the plug wire boots out of the valve covers, but you'll need some compressed air and safety glasses (or something to protect your eyes) to clean them out.
    Don't worry, you are not the first person to do that.
