Usage
How It's Used
Setup
When initially removed from the packaging, the Saturator requires 4 AA batteries for operation (batteries not included). The batteries are inserted through the base of the water gun. After battery insertion, the Saturator needs to be filled with water before it can be used. This process is described in the image below.
