Graveyard Swamp Botanical is a hands-on, plant-powered eruption experience that turns a simple splash of water into a miniature science spectacle. Each batch is lovingly hand-mixed from marigold petals and plant-based powders, bound with baking soda, and housed in a 100ml plastic tub that’s reusable and fully recyclable. Expect a little variation in color from batch to batch—that natural variation is part of the charm of this craft kin of eruption kit.
What’s inside
- 100ml plastic tub (reusable & fully recyclable)
- Erupting Botanicals made from marigold petals, plant-based powders, and baking soda (sodium hydrogen carbonate)
- Each batch is hand-mixed for a unique, artisanal touch
- All components are plant-based; color and texture may vary slightly due to the handmade process
- Produced in a facility that may encounter common allergens such as wheat, dairy, celery, eggs, and nuts
How it works
Just add water and watch the magic unfold. The eruption is powered by a familiar fizzing chemistry, where safe fizzing reactions reveal a dynamic swirl of color and texture. Marigold petals drift through the fizzy mass as the potion brightens the air with a playful, swamp-inspired ambiance.
Why Graveyard Swamp Botanical stands out
- Plant-based, handcrafted quality—a smaller-batch approach that emphasizes natural ingredients and care in every mix
- Sustainable packaging—a 100ml tub that’s reusable and fully recyclable
- Visible learning moments—observe chemical reactions, color changes, and the way plant-based materials interact with water
- Safety-conscious design—clear supervision guidelines and hands-on activities that blend education with safe play
Safety, supervision, and handling
- Adult supervision is required when performing the experiments, as the kit uses fizzy mixtures that involve acids and bases
- Avoid contact with eyes; if eye contact occurs, rinse cautiously with water and seek medical advice if irritation persists
- Set up in a well-lit area with access to water, and keep the workspace clear of obstructions
- Dispose of chemicals responsibly in accordance with national regulations; do not pour down the sink without proper guidance
- Be aware that the kit includes substances such as citric acid and sodium hydrogen carbonate; mishandling can cause harm
Who this is for
- Families looking for a hands-on science activity that’s also visually captivating
- Educators seeking an engaging, safe demonstration of basic chemistry and plant-based materials
- Birthday parties or themed play that invites curiosity and exploration in a controlled, supervised setting
Tips for the best experience
- Prepare a dedicated, clean workspace with a water source approachable for quick rinses
- Discuss the safety rules with supervising adults before starting, so everyone knows what to expect
- Use within the provided tub to keep the experience tidy and contained; the tub’s material supports repeated use
Care and sustainability
The Graveyard Swamp Botanical kit is designed with sustainability in mind. The 100ml tub is reusable and fully recyclable, and the botanical mixtures are plant-based. After your activity, follow local guidelines for disposing of the fizzy residues and rinse the area well to keep materials ready for the next magical eruption.

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.
