From materials we need an incandescent lamp, fine-grained aquarium soil and a small aquatic plant.
To begin, separate the bulb from the bulb bulb. This can be done with a hammer by tapping it on all sides of the base. Just do not apply excessive force - the lamp may break.
After removing the cap, remove unnecessary glass parts from the bulb. File the edges of the hole in the flask if they are too sharp.
Rinse the flask and pour aquarium soil into it. Then plant an aquarium plant in it and fill the lamp with water. To top it, put on the cap. The resulting aquarium can be put on a stand or suspended if the base holds well on the flask.
Of course, in such an "aquarium" to keep the fish will not work. But with the help of it you can surprise your friends and acquaintances. Also, an aquarium in a light bulb can be an original gift.
