- Add a few drops of food coloring; your choice of color.
- Break an Alka-seltzer tablet into a few small pieces, and drop them in the flask one at a time.
- Watch your lava lamp erupt into activity!
How do you explain a lava lamp experiment?
The Alka Seltzer reacts with the water to make bubbles of carbon dioxide. The bubbles attach themselves to the blobs of colored water and bring them to the top of the glass. When the bubbles pop the blobs of colored water fall back to the bottom of the glass. This lava science experiment is sure to WOW your kids.
How do you make lava with flour and water?
Mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil and 2 cups warm water. The mixture should be smooth and firm. Add more warm water if needed. Stand the soda bottle in the baking pan and mold the dough around it into a volcano shape.
How do you make water look like lava?
What to do. Fill the glass about 3/4 full of water . Add about 5 drops of food coloring – I like red for the lava look. Slowly pour the vegetable oil into the glass.
What is the chemical reaction in a homemade lava lamp?
When the mixture is poured into the glass, it sinks to the bottom and the chemical reaction occurs between the baking soda and vinegar. This endothermic chemical reaction creates carbon dioxide as well as causes the glass to cool noticeably.
How do you make a lava bottle?
How to:
- Fill the bottle a quarter full with water.
- Add a few drops of food colouring until you like the colour you see. You can add glitter too.
- Fill the bottle almost to the top with vegetable oil. Let the mixture separate.
- Break up two Alka-Seltzer tablets and drop them in the mixture. Watch your lava lamp bubble!
What is a lava lamp filled with?
The whirling globs we remember are made mainly of paraffin wax, with compounds like carbon tetrachloride added to increase its density. The liquid the wax floats in can be water or mineral oil, with dyes and sparkles added for whimsy.
What is the controlled variable in a lava lamp experiment?
Hypothesis and Variables INDEPENDENT VARIABLE- The temperature of the water. DEPENDENT VARIABLE- We are measuring how well the lava lamp works. CONSTANTS- The amount of water, oil, and salt put in the the container will be about the same. CONTROL GROUP- The control group will be hot lava lamp.
How do you make a lava sensory bottle?

Equipment: * Clear glass * ¼ cup vegetable oil * 1 teaspoon salt * Water * Food coloring [any color] Method: 1 – Fill the glass about ¾ full of water. 2 – Add about 5 drops of food coloring. 3 – Slowly pour the vegetable oil into the glass, see how the
How to make a lava lamp science experiment?
Pour water into the plastic bottle until it is around one quarter full (you might want to use a funnel when filling the bottle so you don’t spill anything).
What is the science involved in a lava lamp?
What is the science behind the lava lamp experiment? When enough bubbles pop, the water-and-remaining gas becomes more dense than the oil. So the ball of water sinks down through the oil and joins the rest of 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.
What are some lava lamp questions for science projects?
What happens when you add water to the plastic bottle? Why do you think this occurs?
