An lava lamp It is a type of lamp typically used more for decoration than for lighting. The gentle flow of randomly formed wax droplets suggests a stream of lava.
This lamp is an invention of the Englishman, Edward Craven Walker, in the 1960s and called it the "Astrolight" or the "Astro Lamp" and presented it at a trade fair in Hamburg in 1965, and then the businessmen Adolph Wertheimer and his Business partner Hy Spector bought the American rights to the product and began producing it as the «Lava Lite®» via a corporation called Haggerty Enterprises and trading under the name «Lava World International @.» The lava lamp became an icon of the 1960s, where the constant change and intense display of color were likened to psychedelic hallucinations.
How to make a lava lamp
The materials needed are:
- Glass bottle (pyrex) resistant to temperature changes, the height of the bottle is approximately 40cm and is tubular in shape.
- Distilled water
- Colorless paraffin
- Baby oil (It must be transparent)
- A spring that is the width of the inside of the bottle.
- Oil dye, (paraffin is made from oil)
- Distilled water.
- For the base you can use a milk can or a can that is the width of the bottle we are using.
- A 40 watt lamp
Drill in the center of its base (the can or cans) to be able to insert the socket and the lamp. Insert the lamp socket, prepare a little plaster and insert it in the bottom of the can, around the lamp socket so that it fits well into the can and acquires the weight you need to hold the bottle. (It takes more than an hour for the cast to dry completely.) When it has dried, place the lamp.
Carefully clean the bottle before use (Otherwise the lava will stick to the surface) It is important that the bottle does not leak when closed. The tip of our lamp (which must be metal too) can be obtained from a soda can without printing. This cap will only be placed on the nozzle of the bottle, without any pressure. The copper spring that will go to the bottom of the bottle is very important since it acts as a breaker of the surface tension for the bubbles that come down and a conductor of heat, which will melt the wax or lava.
Manufacture of lava:
Initially, the bottle should be boiled to remove any impurities that it may contain inside. Then in a pot, melt the paraffin, the melting process is in a water bath (take a pot, add a little water and enter another, smaller pot, and this is where the paraffin is going to melt). While the paraffin is melting, the spring enters the bottom of the bottle. When the paraffin is completely melted, add approximately two tablespoons of baby oil and mix (sometimes the mixture is not very uniform, but when the paraffin dries that problem will be solved)
Once the two components are mixed, pour a little baby oil into the bottom of the bottle (approximately 2 centimeters of oil remain at the bottom of the bottle) then shake the bottle so that there are traces of oil all over the inside.
Then add coloring to the paraffin and enter it inside the bottle with the help of a funnel, ensuring that when the paraffin is poured it does not spill down the walls of the bottle. Wait a few minutes for the paraffin to solidify (you should add about 4 or 5 centimeters of paraffin to the bottle, although the amount will depend mainly on the size of the bottle).
Then fill the bottle halfway with distilled water, if you want you can add a teaspoon of detergent (do not add more than that because otherwise it will generate foam when the bottle heats up) again add baby oil and then again distilled water. Fill up to approximately 4 centimeters before the top. Cover the bottle and wait for the wash to be completely hardened (from 12 hours to a day). The next day the bottle is placed in the refrigerator (not in the cooler), this serves to seal the air gaps that may have been generated within the hardened paraffin (leaving it for a maximum of one hour) after that time warm the bottle a little the bottle remove it and dry it with a cloth.
Then place the bottle on the base of the lava lamp, turn on the lamp and let it heat up, since this is the first time the lamp is going to carry out the process, it may take between 2 and 3 hours.
Caution: When the paraffin is melted after 3 hours it will begin to make small lava bubbles, little by little they will grow in size, never move the lamp while it is working since if you move the melted paraffin you will have to make another one because you will have failed all the process you did.

We have seen how to make lava lamps
Now if you have no excuses to make your lava lamp.
This time I have found some good videos that can complete the information that we presented in their day.
This high school video John Bosch it's excellent.
This other a lava lamp that they made in the anthill.
And finally this video from STK Group.
