What is a gras lampe bad?

A gras lampe bad is a type of lamp that was created in the 1800s. It has a long, thin neck with a small bulb at the end. The light from the bulb is directed down into an elongated bowl of water. When the lamp heats up, it creates bubbles which rise to the top and create light in an area around them.

Gras lampes are popular for their unique design and functionality. They are often used as decorative fixtures in homes or offices.
