I have seen a lot of creative projects which utilize the popular “Bawls” bottles. Other projects had two features which I wanted to improve on;

1: The common use of batteries instead of a more permanent power source

2: The intensely bright spots which LEDs often produce

I based some of my design off of other projects and modified the points I wanted to improve on, this resulted in the Bawls Blue Crystal LED Light seen bellow.
