a few days or weeks. It might even take months depending on how hot the lamp is and how much cold water you're trying to evaporate.
A lava lamp will work better in hot water because the heat helps the wax inside the lamp melt and flow more easily, creating the lava lamp effect. Cold water may make the wax inside the lamp too thick and slow-moving, resulting in a less pronounced lava lamp effect.
hot water contains more energy than cold water. cold water causes the water molegules to vibrate more.
A hypothesis for making a lava lamp could be: "If I combine oil, water, and effervescent tablet in a bottle, then the chemical reaction will cause bubbles to form and rise to the top, creating a lava lamp effect."
The difference between a pole lamp and a normal lamp is very miniscule. A pole lamp stands on a pole and the lights are strung up like they are on a tree.
The manipulated variable in making a lava lamp is the temperature of the lamp, which can be adjusted to control the movement of the colored blobs in the lamp.
The hypothesis for making a homemade lava lamp could be that the combination of oil, water, and effervescent tablets (such as Alka-Seltzer) will create a visual effect resembling a lava lamp due to the reaction between the ingredients causing bubbles to rise and fall in the mixture.
The main problem with making a lava lamp is achieving the right balance of ingredients and heat to create the unique bubbling effect. If the proportions are off or the lamp is too hot or too cold, the ingredients won't interact properly, and the lava lamp won't work as intended. It can take some trial and error to get it just right.
No, you should not put water in an Orbeez mood lamp. The lamp is designed to work with the Orbeez beads and adding water could damage the lamp or cause a short circuit.
Hot/Cold cycle.
A sodium lamp would not disappear when added to water. However the lamp would probably never be usable again.
When you add food coloring to a homemade lava lamp, the coloring mixes with the water and oil in the bottle. As the colored water moves up and down through the oil due to the Alka-Seltzer tablets reacting with water, it creates the mesmerizing lava lamp effect.
