Water phone

While touching a source of water (pool, cup, bottle, or otherwise) you imbue that source of water with a property that allows for infinite communication within the same plane. The water source cannot contain more water than what would be needed to fill a tub. After imbuing a source of water with this property the caster must add a name to this source. For example a code name, the name of a person, or the name of a place, etc. Once created anyone may use this source of water for communication. Though everyone must follow the rules below regarding the number of 'calls' one can make in a long rest.

This water transmits both noise and an image of whatever the water is reflecting. Allowing the users to see and hear each other (and possibly their environment). 

The caster may imbue any number of water sources to potentially contact. However, you are only given 1 free 'call' for each long rest. The caster may however upcast this spell to be able to contact more than 1 source of water per long rest. Each call costs 1 spell slot of first level or higher.
