What You Need for a New Year’s Confetti Experiment

• Clear plastic champagne flutes or cups, so kids can watch the reaction happen
• Baking soda, the base that starts the fizzing reaction
• Vinegar, the acid that reacts with the baking soda
• Food coloring, for vibrant, celebratory colors
• Glitter or confetti-style glitter, for that sparkling New Year’s touch
• A tray or bin to contain spills and keep cleanup easy
• A small measuring cup or squeeze bottle for pouring vinegar with control

How to Set Up This New Year’s STEM Sensory Activity

1. Place a clear plastic flute inside a tray or large bin to keep spills contained.

2. Add a few spoonfuls of baking soda into the bottom of the flute.

3. Sprinkle in some glitter and add a few drops of food coloring on top of the baking soda.
4. Give the measuring cup or squeeze bottle to your child and let them slowly pour vinegar into the flute.

5. Watch together as the colorful confetti fizzes and bubbles up and over, just like a sparkling celebration.

6. Repeat with new flutes and different color combinations to keep the experiment going.

Ways to Play This New Year’s Sensory Bin

• Set up several flutes with different food coloring combinations and compare the results side by side
• Let kids control how much vinegar they pour to see how it changes the speed and height of the fizz
• Mix two colors in one flute and watch them swirl together as the reaction happens
• Encourage kids to narrate what they see, hear, and smell during the eruption
• Use different amounts of glitter to see how it affects the look of the confetti bubbles
• Turn it into a countdown by setting up multiple flutes and pouring them one after another

Skills Kids Build in This New Year’s Sensory Play

• Early chemistry concepts: kids see firsthand what happens when an acid meets a base
• Observation and prediction: kids guess what will happen before pouring and compare it to the real result
• Language development: describing colors, sounds, and bubbles builds descriptive vocabulary
• Fine motor skills: pouring, squeezing, and measuring strengthen hand control
• Cause and effect understanding: kids learn that their actions directly change the reaction

Tips and Variations

• For babies and younger toddlers, do the pouring together with hand over hand guidance and keep the focus on watching and talking about the reaction
• For older preschoolers, let them measure their own baking soda and vinegar for added independence
• Add a few drops of dish soap for extra foamy, long lasting bubbles
• Always supervise closely since vinegar can sting eyes and food coloring can stain hands and clothes
• Try it outdoors or in the bathtub for an even easier cleanup

Clean Up and Storage for Your New Year’s Confetti Experiment for Kids

• Rinse the flutes with warm water right away to prevent sticky residue from drying
• Wipe down the tray or bin with a damp cloth to catch any stray glitter
• Store unused baking soda, vinegar, and glitter in sealed containers for your next experiment
• Keep a few extra flutes on hand so you can set up again quickly next time
