|"Mom, open it up |
so I can play!"
The thermometer part actually lights up blue if the water is too cold, green if it's good to go, and red if it's too hot.It activates instantly when it's in water and updates the temperature constantly. I love the fact that it activates and shuts off on it's own. I often forget to turn things off and end up draining the batteries. Another thing I like is that the batteries are actually replaceable and just take 3 AAA batteries... no searching for some funky battery size to keep the thing going.
