Maimonides Minute – Hilchot Kriat Shma 2:7-8 (Communicating during Kriat Shma with gestures)

If someone is standing in a mikvah just as the ideal time for reciting Kriat Shma is about to pass, may he read while standing in the water? When he is reading Shma, may he motion with his hands or eyes in order to communicate?
