The history of lava lamps

Lava lamps, also known as astro lamps, were invented by a British man named Edward Craven Walker in the 1960s. Walker was a former British army engineer.
It was in 1963 that he developed an interest in light effects after seeing a plasma lamp at an exhibition.

Although their principles are completely different, lava lamps and plasma lamps are closely related.

Inspired by this concept, he began experimenting with fluids and liquid solutions in glass bottles.
Walker eventually succeeded in developing a design in which a substance moved in a colored solution (like oil rising to the surface of water; or vinegar).

Following this invention, Walker decided to set up a company called Crestworth to market these lamps under the name "Astro Lamp". The name was later changed to "Lava Lamp" at the suggestion of one of his friends, who compared the lamp's fluid movements to those of magma.

The bubbles and suspended matter of a lava lamp are somewhat reminiscent of molten lava.

Lava lamps rapidly gained popularity in the 1960s and 1970s, before falling somewhat into disuse during the 1990s. Walker's company was eventually renamed Mathmos, and continued to produce his lamps, albeit in smaller quantities.
(The Mathmos company is still active today!)

Over time, the lava lamp has become a symbol of the 60s and 70s, and of retro kitsch in general. They have since become collector's items and emblematic decorative elements of those decades.
Robert Craven Walker died on August 15, 2000 at the age of 82.

How does a lava lamp work?

The operation of a lava lamp is based on a simple principle involving the difference in density between two liquids and the variation in temperature.
Wax and colored liquid are usually contained in a glass bottle. A bulb in the base of the lamp heats the bottle and the liquid inside from below. This melts the wax, which then travels up and down the lamp.

Note: heating time may vary depending on the bulb. It's also worth noting that the ambient temperature of the room can influence the way the light works.

The basic principle of the lava lamp could be compared to that of vinegar in water (two liquids that don't mix).
In the case of vinegar and oil, the molecules of both substances are more attracted to their own molecules than to the molecules of the other substance. This is why vinegar and oil don't mix.

Let's see how a lava lamp works in general:

• Base and bulb: the base of the lava lamp contains a bulb, which heats and illuminates the lamp from below.
  
  
• The liquids: inside the lamp's glass container (often bottle-shaped), there are two immiscible substances. Usually, one is a colored liquid composed mainly of water; the other is wax.
  
  
• Heating: when the lamp is switched on, the bulb in the base heats the liquid and the wax. The heat produced by the bulb melts the wax.
  
  
• The heating and rising cycle: under the effect of heat, the wax eventually melts and its density becomes less than that of the liquid. Now malleable and less dense, the wax rises by itself to the top of the luminaire tube.

• Bubbles and cooling: as it rises to the top of the container, the wax comes into contact with the least hot part of the liquid, as it is towards the top of the lamp.
  
  
• Movement: as it reaches the top (towards the surface) and cools, the wax changes density once again, eventually sinking to the bottom. As it does so, it crosses the rest of the wax, which is still hot and rises again. This creates the movement typical of lava lamps, where bubbles can be seen criss-crossing the tube. All this is actually caused by the heating and cooling of the wax!
  
  
• The cycle: back towards the base of the container, as close as possible to the lamp, the wax can heat up. As its temperature rises again, and its density falls, the wax rises again. As it does so, it crosses the wax, which moves back down, and so on.

This cycle of heating, rising and cooling creates the characteristic hypnotic patterns seen in a lava lamp. The combination of fluid wax movements, bubbles and colors creates a fascinating ballet that has made the lava lamp a popular object.

To summarize: In the case of the lava lamp, as in the case of oil in vinegar, two immiscible liquids with a difference in density produce characteristic movements when the density changes due to heat (in the case of the lava lamp) or dissolution (in the case of oil in water).

Vinegar and oil: it's all a question of molecules!

How to make a homemade lava lamp

Would you like to try out a fun experiment at home, or understand the lava lamp principle a little better?

Making a homemade lava lamp with oil, vinegar and dye can be a fun and creative project!

Materials required:

• Clear glass bottle
• Vegetable oil
• White vinegar
• Food coloring
• water
• Alum (optional, to stabilize bubbles).

Instructions:

• Fill the glass bottle with vegetable oil to about 3/4 of its capacity.
  
  
• In a separate bowl, mix white vinegar with water. Use approximately 1/4 vinegar to 3/4 water. You can adjust the quantities according to the size of your bottle and the desired height of your lamp!
  
  
• Add a few drops of food coloring to the vinegar and water mixture. Mix well to obtain the desired color for your bubbles.
  
  
• Slowly pour the colored vinegar mixture into the oil-filled bottle. Be sure to pour gently to avoid creating too many bubbles.
  You can also add a small amount of alum (a double sulfate of aluminum and potassium) to the vinegar and water mixture to help stabilize the bubbles.
  
  
• Once you've added the vinegar mixture to the oil bottle, you should see bubbles forming and slowly moving down through the oil. If the bubbles don't go down, you can ' the bottle to help them form.
  
  
• To activate your lava lamp, place a flashlight or small LED light under the bottle. The heat from the lamp will warm the vinegar and water mixture, creating bubbles that will rise through the oil.

You can experiment with different colors of food coloring and ratios of water to vinegar to achieve the desired effect! (You can also use bicarbonate. Bicarbonate and vinegar are known to react!)
