Ingredients
  

  • 1/2 cup warm water
  • 1/4 cup vinegar any white vinegar
  • 1 tbsp baking soda
  • 1 tsp citric acid
  • 1 tbsp rainbow glitter mix
  • 1 tsp glow-in-the-dark powder or paint
  • red food coloring a few drops
  • yellow food coloring a few drops
  • blue food coloring a few drops
  • green food coloring a few drops
  • 1 tsp dish soap

Equipment

  • Clear plastic bottles with lids
  • Small glow sticks or waterproof LED lights
  • Larger measuring cup
  • Spoon

Method
 

  1. Step 1: Prepare the Glow Base: First things first, grab your two clear plastic bottles. Carefully place one glow stick or waterproof LED light into each bottle. This is what's going to give your "lightning" its brilliant internal glow! If you're using glow sticks, crack them now to activate them for maximum glow.
  2. Step 2: Mix the Rainbow Potion: Now, let's get a little messy (the fun kind!). In a separate cup – I usually use a larger measuring cup for this – stir together your warm water, vinegar, a good squirt of dish soap, the glow powder (or paint if you're using that), and a few drops of each food coloring. Give it a really good stir until everything is wonderfully combined and vibrant. You'll want to see those colors swirling! Once it’s mixed, carefully divide and pour this colorful concoction into both of your prepared bottles, making sure not to fill them all the way to the top – you need room for the fizz!
  3. Step 3: Add the Sparkles: Time for the razzle-dazzle! Sprinkle a generous amount of that fabulous rainbow glitter into each bottle. Don't be shy here; the more glitter, the more spectacular your "lightning" will be! I find that a mix of fine and chunky glitter gives the best effect.
  4. Step 4: Start the Bubbling: This is where the real magic begins! Add a tablespoon of baking soda to each bottle. Then, quickly, drop in a teaspoon of citric acid. Watch closely – you'll see it start to fizz almost immediately!
  5. Step 5: Seal and Shake: As soon as you add the citric acid, quickly close the bottles tightly with their lids. Now, gently – and I mean gently – shake them. You'll see an incredible reaction as the ingredients combine, creating a swirling, bubbling, glowing rainbow lightning storm right in your hands! It’s truly mesmerizing to watch the colors and bubbles dance.

Notes

Customize your bottles with fluorescent paint or different types of glitter, sequins, or confetti. You can also add small plastic toys, beads, or a few drops of essential oil. Ensure bottles are clean and dry, and lids seal tightly. Don't overfill, leaving headspace for bubbles. Mix the colored liquid base thoroughly. Act quickly to seal the bottle once baking soda and citric acid are added. The liquid base can be prepped ahead, adding fizzing agents just before use. Adult supervision is recommended. For a lasting glow, waterproof LED lights are fantastic. Store sealed bottles upright, away from direct sunlight; the initial fizz is a one-time event, but the shimmer and colors will last. These bottles are not meant for consumption.
