Answer:
hey!!
Explanation:
objects needed:
=>A transparent container, like an empty water or soda bottle
=>Water
=>Vegetable oil
=>Food colouring
=>An effervescent tablet (like Alka-Seltzer®)
=>A flashlight (optional)
How to make a lava lamp:
Fill one-quarter of the bottle with water
Add food coloring
Fill the rest of the bottle with vegetable oil
Add half an effervescent tablet
Optional: if you have a flashlight, go to a dark room, turn on the flashlight and watch your groovy new lamp in the dark!
sceince behind this is : when the Alka-Selzer tablet is dropped in the oil and water, it sinks to the bottom because it is denser than oil and denser than the water. ... Changes in density as gas is added to or taken away from water cause it to float up and sink down through the oil. Thus the lava lamp is created!
