What is the science behind blobs in a bottle?
Molecular polarity basically means that water molecules are attracted to other water molecules. They get along fine, and can loosely bond together (drops.) This is similar to magnets that are attracted to each other. Oil molecules are attracted to other oil molecules; they get along fine as well.
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. Thus the lava lamp is created!
What do you need for blobs in a bottle?
BLOBS IN A BOTTLE
- A clean 1 liter clear soda bottle.
- 3/4 cup of water.
- Vegetable Oil.
- Fizzing tablets (such as Alka Seltzer)
- Food coloring.
What is bottle experiment?
When you cover up the lid to the bottle, the water is pulling down but that air up in the top of the bottle is becoming a vacuum. That means “low pressure.” The air pressure outside the bottle is higher, so it actually tries to push into the bottle through the bottom hole.
What can replace Alka Seltzer in a lava lamp?
Alka-Seltzer Tablet or alternative including:
- Mixture of baking soda and citric acid.
- Baking Soda and Vinegar.
- Table Salt.
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.
What is the dependent variable in a lava lamp experiment?
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.
Can you make a lava lamp with aspirin?
Students make a simple yet spectacular lava lamp using coloured water, vegetable oil and a soluble aspirin tablet.
How do you make an experiment in a bottle?
Go With the Flow: Add some liquid soap and food coloring to a plastic bottle, and then fill the bottle to the top with water. Cap the bottle tightly, and then twirl it gently to see what kinds of patterns happen with the ingredients.
What do you think happened to the molecules when the plastic bottle was being squeezed?
When you let the bottle pop out, the air pressure in the bottle decreased along with the temperature. This caused the water molecules to condense into a cloud. With a partner answer these questions: Liquid water evaporates and becomes water vapor (note how the terms are similar).
Can I use baking soda instead of Alka-Seltzer?
Note: If you don’t have Alka-Seltzer ® tablets, you can use a pinch of baking soda and a drop of vinegar instead.
