At MGM, there is the Singing in the Rain Umbrella across from the LMA theatre, if you have someone stand on it and you stand outside, you get nice and wet, on NY Ave there is a Fire Hydrant that sprays, across from Backlot there is the misting Coke bottle and misting truck radiator and finally, in the HISTK Playground there is a hose and a super soaker that really work. If you want to get wet late at night, sit in the first row at Fantasmic (we get wet everytime)......those are the ones that I can think of......
