Top 5 experiment about lava lamp

A lava lamp (or Astro lamp) is a decorative novelty item, invented in 1963 by British accountant Edward Craven Walker, the founder of the British lighting company Mathmos. The lamp consists of a bolus of a special coloured wax mixture inside a glass vessel, the remainder of which contains clear or translucent liquid, the vessel is then placed on a box containing an incandescent light bulb whose heat causes temporary reductions in the density and viscosity of the wax. The warmed wax rises through the surrounding liquid, cools, loses its buoyancy, and falls back to the bottom of the vessel in a cycle that is visually suggestive of pāhoehoe lava, hence the name. The lamps are designed in a variety of styles and colours.

Raw material

As noted above, the actual ingredients used in Lava Lite Lamps are proprietary but there are several liquid ingredients, which can be combined to give a lava effect.

Liquid Component

Lava-type lamps can be made with water mixed with isopropyl alcohol as one phase and mineral oil as the other. Other materials, which may be used as oil phase ingredients include benzyl alcohol, cinnamyl alcohol, diethyl phthalate, and ethyl salicylate.

Other additives

Other additives used in lava lamp fluids include various oil and water-soluble colorants. The specific gravity of the aqueous phase can be adjusted through the addition of sodium chloride or similar materials. In addition, a hydrophobic solvent may be added to the mixture to help the lava coalesce. Turpentine and similar paint solvents are said to work well in this regard. Antifreeze ingredients can also be added to increase the rate at which the lava warms.

in here, we wil made lamp from household ingredients, these instructions to made lava lamp with household ingredients such as vegetable oil, food coloring, alka-seltzer ets.
1. Rinse out a large soda or water bottle.
Any tightly sealable container works, but you probably have an empty water bottle laying around somewhere. Try to find one that holds at least 16 ounces or 500 milliliter, so you can clearly see the display. This method is safe for kids to follow on their own, and much faster and easier than making a permanent lava lamp. Young kids can ask an adult to do the pouring for them.

2. Add oil, water, and food coloring to the bottle. Fill the bottle ¾ of the way full with vegetable oil, then top it off with water and about 10 drops of food coloring (or enough to make the solution appear fairly dark).

This is material and tool to made lava lamp
1. Clean, plastic soda bottle with a cap (16-ounce size works well)
2. Vegetable oil (the cheaper the better)
4. Alka-Seltzer tablet

5. Large flashlight6. Water

How is made

  1. Fill the bottle three-quarters full with vegetable oil.

2. Fill the rest of the bottle with water (almost to the top but not overflowing).

Material

Flask or bottle

Vegetable oil

Water

Food coloring

Alka-seltzer

How to do

  1. Fill the flask most of the way with vegetable oil.
  2. Fill the rest of the flask with water. The water will sink to the bottom under the oil.
  3. Add a few drops of food coloring; your choice of color. The food coloring is water-based, so it will also sink and color the water that is now at the bottom of the flask.
  4. Break an alka-seltzer tablet into a few small pieces, and drop them in the flask one at a time.
  5. Watch your lava lamp erupt into activity! As the reaction slows down, simply add more alka-seltzer.

Material

Tall glass, glass jar or plastic cup

water

food dye

oil

Alka-Seltzer tablets (or other effervescent tablets)

Procedure

  1. Fill glass ⅓ with water and add a couple of drops of food dye.
  2. Carefully float oil on top of the water, filling the glass to about 1cm from the rim.
  3. Break the Alka-Seltzer tablet into 4 parts and gently drop them into the glass.
