Lava Lamps

That would depend on what type of turtle or reptile you are referring to. All animals do need a break from the UV's at some point.

No, a lava lamp is not considered a type of optical device.

No. There are no models available that can analyze a specific lava lamp and predict the pattern of the wax suspended in the oil. There are too many specifics that vary from one lamp to another. The specific position of the lamp in the base, for one. The continually varying temperature of the wax, oil, container, ambient surroundings. All of these things and more are involved in the creation of the patterns observed.

The unique lamps were created by a British inventor and former World War II pilot, Edward Craven-Walker, who reportedly thought up the idea after seeing a homemade, liquid-filled egg timer at a pub.

In September of 1963, Craven-Walker started a company to research and develop his invention. But his widow, Christine Baehr, told BBC News they had a rough time, at first, trying to find investors.

But Baehr said that, after the couple took their product around the British countryside in a van, word of the wildly original illumination spread. Pretty soon lava lamps could be seen in science fiction movies and television shows like "Dr. Who," and became extremely trendy. By the mid-1960s, according to an MIT report, lava lamps "had exceeded 7 million units worldwide."

Baehr told The Associated Press that she knew the lava lamp had "made it" as a product when she heard that Beatles drummer Ringo Starr had purchased one.

Don't - You replace the wires just as you would for the original wiring but you must use a lower guage wire size - meaning a thicker wire. The AC cord for lamps in the past 30 years was at least good for 500 watts. Don't forget that the wattage rating my not be limited by electrical considerations but by thermal limits. A larger bulb may melt or burn the fixture itself, not just the socket.

Hot/Cold cycle.

The wax substance is more dense than the liquid when cool and less dense than the liquid when heated. The wax moves by density convection.

Well there is a metal springy at the bottom of your lava lamp, It helps heat the lava (wax) in the bottle.

Incandesent round mini-bulb designed specifically to fit into lava lamp with appropriate wattage to heat the volume of the lamp to a temperature that melts the wax compound without overheating the liquid volume. Very precise so use only the manufacturer's recommended bulb.

To determine the length of the string needed, Brenda can calculate the circumference of the circular bottom edge using the formula: circumference = π * diameter. The circumference of the lamp shade is 16π cm, so Brenda will need a string of 16π cm in length to attach the beads along the circular bottom edge.

why does the lava sink or rise?

Yes it wont over heat its perfectly safe, you may go thru bulbs a bit quicker.

One lamp won't do much. I have 10 and my room is always really hot when they are all on

A lava lamp demonstrates a physical change. The wax in the lamp changes states from solid to liquid and back to solid again as it is heated and cooled, but the chemical composition of the wax remains the same throughout the process.

idkk who cares;p

The give of light to see by but also provide a source of movement that gives a room "mood" - sort of like watching the flames of a flickering fire. It helps you relax.

It is just for decoration

No, Flumocil is a medication used to treat respiratory conditions by helping to clear mucus from the airways. It is not designed or effective for use in a lava lamp.

If the lava lamp wax is not melting, it may be due to the bulb not providing enough heat. Ensure that the lamp is plugged in and turned on for sufficient time to allow the wax to melt. If the issue persists, the lamp may be defective and need to be replaced or repaired.

You can sell your oil rain lamp on various online marketplaces like eBay, Etsy, or Facebook Marketplace, where collectors and vintage enthusiasts often look for unique items. Local thrift stores, flea markets, or antique shops may also be interested in purchasing or consigning your lamp. Additionally, consider posting on social media groups dedicated to vintage or home decor to reach potential buyers.

The controlled variables in a lava lamp experiment could include the type and amount of wax and liquid used, the size and shape of the lamp, the temperature of the room, and the power of the light bulb. These variables are kept constant to ensure that any changes in the lava lamp's behavior are due to the manipulated variable being tested.

The dependent variable in a lava lamp experiment could be the height of the blobs or the speed at which they move up and down. The dependent variable is the aspect of the lava lamp's behavior that is being measured and potentially affected by changes in the independent variable.
