I made one of these a few years years ago for my sixth grade science class. It is pretty easy. Here is what you need.
Ingredients
1.Small water bottle (empty)
2.Olive oil
3.Food coloring
4.water
First you mix the water and food coloring together (until you get desired color)
Then u put the oil in the empty water bottle, add the food coloring and water to the conquotion the tighten the cap and shake.
The reason the oil doesn't mix with the water is because the density of the liquids is far to different to combine and or to mix.
You should try it, it's cool fun and interesting.
why does the lava sink or rise?
some kind of heat sensitive goo, and probably dye.
There are many ways. Do some research. ^^haha. no but seriously.
the lava lamp invented by edward craven walker Electrocardiograph in Leyden Hospital, Netherlands
Target, Walmart, amazon and eBay carry different brands and colors of lava lamps that are for sale. For Target and Walmart, lava lamps can be purchased online or directly from the local store.
Singapore-born inventor Craven Walker was having a pint in post W.W.II England. The pub's decor included a fascinating lamp, which Craven Walker described as a "contraption made out of a cocktail shaker, old tins and things." It was to become the starting point and inspiration for Craven Walker's design. The liquid-filled inventor proceeded to purchase the equally liquid-filled lamp, whose creator (Mr. Dunnett) Walker later discovered had died. Walker became determined to make a better version of the novelty item and spent the next decade and a half doing so (inbetween running an international house-swap agency and making films about nudism.) Walker worked on improving the lamp with his company the Crestworth Company of Dorset, England. Initially local retail merchants thought his lamps were ugly and disgusting. Luckily, for Craven Walker the "Psychedelic Movement" and the "Love Generation" came to dominate 60's merchandising in Great Britain and sales of the lava lamp soared. It was the perfect light for modern times, Walker declared. "If you buy my lamp, you won't need to buy drugs." Craven Walker perfected a secret Lava recipe of oil, wax and other solids. The original model had a large gold base with tiny holes to simulate starlight, and a 52 oz. globe that contained red or white Lava and yellow or blue liquid. He marketed the lamp in Europe under the name of Astro Lamp. Two American entrepreneurs saw the lava lamp displayed at a German trade show and bought the rights to manufacture the lava lamp in North America under the name Lava Lite lamp. Before selling his company, sales of the lamps had exceeded seven million units. Today with over 400,000 lava lamps made each year, the Lava Lamp is enjoying a comeback. Craven Walker's originally company, the Crestworth Company, changed names to Mathmos in 1995 (a reference to the bubbling force in Barbarella.) They still manufacture the Astro, Astro Baby, and more Lava Lamps in their original home of Poole, Dorset, UK.
The "lava" is a mixture of carbon tetrachloride, mineral oil and paraffin wax. The liquid it floats in is water. The light source is a 40-watt light bulb. When the bulb melts the wax, it will do the lava thing on its own.
Never. It might seem like a good idea to some guys, and I guess what type of guy you are matters too, but in most cases, no.
Acidic lava and basic lava.
Lava Lamps are quite peaceful. The lamp is basically made for vision entertainment. There is no noise. The lamps are groovy and feels like meditation.

Water and oil will separate if the two are combined. The water will be at the bottom while the oil site on top. Just like in a lava lamp some colors float while others sink.
