Somewhere over the rainbow potion kit invites curious kids to leap into a world of magical fizz, color, and imagination. This isn’t just pretend play—it's a hands-on, child-friendly science experience that blends wonder with gentle chemistry for endless imaginative adventures at home.

Designed to spark storytelling as much as science, the kit centers on a safe acid–base reaction: water brings together citric acid and sodium hydrogen carbonate to create a lively fizz, turning every pour into a tiny spectacle of bubbles and color. Along with carefully curated botanical accents, shimmer from glitter and mica, and soothing scent from essential oil, your young alchemist can craft glowing potions with a rainbow of effects.

What’s inside the kit

  • Citric acid
  • Sodium hydrogen carbonate (baking soda)
  • Glitter and mica for sparkle
  • Dried petals for a natural touch
  • Water and essential oil for scent and mood
  • Epsom salt for texture
  • Loose parts to customize and decorate
  • Safety glasses and a spatula
  • Empty mini bucket or coconut bowl (if supplied with your chosen kit)
  • Fractionated coconut oil for mixing and aroma
  • Instruction card and any extra dry ingredients needed for experiments

How to make magic happen

  • Pour water into a bowl and add your “gizzing dust” from the kit, along with a pinch of the dry ingredients.
  • Drop in the fizzing base (citric acid and baking soda) and watch a vibrant, bubbly reaction rise—colors bloom, and the potion swirls with playful motion.
  • Customize the experience by adding petals, glitter, or essential-oil twists to create a unique rainbow potion every time.

Who this is for and how it helps

  • Ideal for curious children who love science, magic, and creative pretend play.
  • Great for rainy-day activities, birthday party crafts, or classroom-style demonstrations that feel more like storytelling than a worksheet.
  • Encourages safe, supervised exploration of basic chemistry concepts (acids, bases, reactions) through hands-on experimentation.

Safety and supervision

  • Adult supervision is required. The kit contains reactive ingredients that can be harmful if misused.
  • Follow the included safety guidance: work in a well-lit, ventilated area away from food, wear eye protection, and keep the workspace clean during and after experiments.
  • Important disposal note: don’t pour chemicals down the sink—dispose of them in accordance with local regulations and supervision guidelines.

Practical tips for best results

  • Set up a dedicated crafting station with a sturdy surface to protect tables and enables easy cleanup.
  • Keep a small bowl of water nearby for quick rinses and to help children control the fizzing reactions safely.
  • Encourage kids to imagine a story behind each potion—What rainbow spell are they casting? What color will appear next?

With Somewhere over the rainbow potion kit, ordinary ingredients become a portal to magical play and discovery. It’s more than a toy—it's a doorway to curiosity, color, and hands-on science that kids will want to revisit again and again.

We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!


RETURNS

We Have Lots More Like This.........

Hello, we are Sostter....

Sostter began, as all good ideas do, with a lively conversation and a shared sense of frustration. Why had the world of independent design become so serious, so samey, so… beige? Where was the spark, the imagination, the sheer joy of discovering something that made you stop and stare?

We dreamt of a marketplace that celebrated difference — where curious minds could explore a world of independent brands, design-led makers, and thoughtful artisans. A space that felt exciting, human, and beautifully imperfect. Today, Sostter brings together remarkable people and their creations — from London to Lausanne, Brooklyn to Berlin — uniting makers and discoverers through craftsmanship, creativity, and conscience.

Every object tells a story, and every purchase supports an independent brand doing things differently. Explore our British makers, discover sustainable brands, browse women-led businesses, find the perfect gift for her, or simply wander through our new arrivals and see what finds you.

This is just the beginning. But enough about us — read all about us, or step inside and see what catches your imagination.
