Why does the Alka-Seltzer tablet cause the colored water to rise and fall in the homemade lava lamp?

To make a homemade lava lamp, the following materials are NOT needed: None of the options listed (all materials are necessary)
The colored water in the homemade lava lamp rises and falls due to density changes caused by the reaction between the Alka-Seltzer tablet and water
The Alka-Seltzer tablet's purpose is to react with water to produce carbon dioxide gas, which gets trapped in the water, causing it to rise
The main science concept used to make a homemade lava lamp is density and buoyancy
The oil in the homemade lava lamp serves as a density separator, allowing the colored water to rise and fall
When the Alka-Seltzer tablet is added to the water and oil, it reacts with water to produce carbon dioxide gas, causing the colored water to rise
To make a homemade lava lamp, you should use vegetable oil or a similar type of oil with a density lower than water
The food coloring's purpose is to add color to the water, making the lava lamp effect more visible
The Alka-Seltzer tablet causes the colored water to rise and fall because it produces carbon dioxide gas, which gets trapped in the water, changing its density and causing it to rise and fall in the oil
