First, he took a PET bottle and cut it into two parts along the line shown below:
I made a hole in the bottom with a diameter of about 3 mm:
I took a polypropylene box for carrying sandwiches, cut a hole of such a diameter in its lid that the bottle went tight:
He painted the box and lid in black:
He began to clamp the bottle in the hole:
From the inside, I inserted a fitting of a porous stone into the 3-mm hole in the bottom of the bottle, which aquarists use to make many small bubbles (such stones are commercially available at pet stores), connected the hose, and carefully sealed everything:
I installed a five-volt aquarium pump (they exist!), A five-volt LED controller, a board with a Micro USB socket and switches:
A five-volt LED strip is rare, but the master found it in such a quantity that it was enough to wind three whole turns on the bottle:
He filled the bottle with water, and on top covered it with a polymer clay cap, also painted black:
This video shows not only the manufacturing process of the lamp, but also the effects that it provides:
