Simple bubble lamp



This is the kind of decorative fixtures that will never go out of fashion, along with lava lamps, tornado lamps and lamps with floating pieces of foil. The author of Instructables under the nickname shalbk made such a thing do it yourself at home.

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:
