Sugar & Vinegar Fireworks in a Cup Science Experiment for Kids
Have you ever seen fireworks bursting in the sky? Now imagine creating tiny fireworks inside a cup! In this fun science experiment, sugar, vinegar, and colorful liquid create a beautiful firework-like burst that spreads through the water. It’s a simple and exciting way to see how liquids move and mix!

Students observe vibrant liquid reactions, creating playful, sparkling visual effects
Let’s Understand the Concept
This experiment shows density and liquid movement.
- Density means how heavy something is compared to its size.
- Some liquids are heavier (denser) than others.
- Adding sugar makes the liquid heavier than water.
- The mixture sinks and spreads, creating a fireworks-like effect.
Materials Required
- Clear plastic or glass cups
- Water
- White vinegar
- Sugar
- Food coloring
- Spoon
- Small mixing bowl
Step-by-Step Instructions
Step 1: Fill the Cup
Fill a clear cup about ¾ full with water.
Step 2: Prepare the Color Mix
- 2–3 spoons of vinegar
- Food coloring drops
- 1–2 spoons sugar
Step 3: Mix Well
Stir until sugar dissolves.
Step 4: Create the Fireworks
Slowly pour the mixture into the water.
Step 5: Watch the Magic!
The colors spread like tiny fireworks.
