Introduction
A lava lamp (or Astro lamp) is a decorative novelty item, invented by British accountant Edward Craven-Walker in 1963. The lamp contains blobs of colored wax inside a glass vessel filled with clear liquid; the wax rises and falls as its density changes due to heating from an incandescent light bulb underneath the vessel. The appearance of the wax is suggestive of pāhoehoe lava, hence the name. The lamps are designed in a variety of styles and colours.
The underlying fluid mechanics phenomenon is a form of Rayleigh–Taylor instability.
The bulb is normally 25 to 40 watts. Generally it will take 45–60 minutes for the wax to warm up enough to freely form rising blobs, when operating the lamp at standard room temperature. It may take as long as 2 to 3 hours if the room is below standard room temperature.
Background of the Study
With the Bubbling Lava Lamp, you 'll learn how to make a homemade, kid-safe lava lamp using materials right in your home. It impresses you everytime not only you but also your friends and neighbors.
Objectives
The lava lamp is used as a visual attractiveness on houses, parties, streets and everywhere that makes people impress. You can learn how to make a homemade lava lamp with your kids right in your home.
