Food coloring (assorted colors)
Alka-Seltzer tablets (or equivalent effervescent tablet)

Small funnel (optional)

Step-by-Step Instructions

Step 1: Prepare Your Jar

Start by thoroughly cleaning the glass jar. Make sure it’s dry before you begin.
Use the funnel (if available) to pour water into the jar, filling it about one-quarter full.

Step 2: Add Oil

Slowly pour vegetable oil into the jar until it’s nearly full. Leave some space at the top (about an inch).
Watch as the oil and water separate, creating a beautiful two-layer effect.

Step 3: Add Color

Add a few drops of food coloring to the water. Observe how it sinks and mixes with the water.
You can choose multiple colors for a dazzling effect; just be mindful of the result.

Step 4: Create the Lava Effect

Break an Alka-Seltzer tablet into small pieces.
Drop one piece into the jar and watch the magic happen! The fizzy reaction will create the lava effect.
If the fizz dies down, you can add more Alka-Seltzer to reset the effect.
Tips & Variations

Customize Colors: Play with different food colors to create unique blends.
Add Glitter: For a cosmic sparkle, mix in some glitter with the water.
Different Jar Sizes: Experiment with varying jar sizes to adjust the visual impact.
Use Different Oils: Try using colored oils for varied visual effects.

Frequently Asked Questions

Q1: Can I use different types of containers?
A: Absolutely! Any clear container will work, but ensure it can hold the liquid without leaking.

Q2: What if I don’t have Alka-Seltzer?
A: You can use other effervescent tablets found in stores, or baking soda and vinegar for a similar effect.

Q3: Will this last long-term?
A: The water and oil will remain separate, but the effect will diminish without adding fresh effervescent tablets.

Q4: Can I use flavored oil or colored water?
A: While flavored oils might provide a scent, they could alter the density. Stick with simple vegetable oil for best results.
