Fizzing Bath Bombs Kit

This kit serves one of our pillars: Natural Production — technology in the service of nature.

Mix the science of an acid and a base to make bath bombs that fizz and foam in water. A delicious-smelling chemistry experiment you can shape, colour, and actually use — or gift.

What's inside the kit?

• Citric Acid ×2 — Citric acid — the fizz
• Sodium Bicarbonate (Baking Soda) ×3 — Baking soda — the base
• Mica Color — Red — Natural mica colour
• Silicone Soap Mould — Silicone mould to shape them
• Honey Fragrance Oil — Fragrance

How the idea works

Every part in the kit has a job. Assembled in the right order they stop being loose parts and become a working system — one you build yourself, understand at every step, and see the result of with your own eyes. The included build guide walks you from zero to running.

Your journey: from kit to competition

• Build — assemble the kit and get it running.
• Understand — learn why each part is there and how it works.
• Improve — modify it, add a sensor, tune it, try your own idea.
• Make a project — turn the experiment into a project that solves a real environmental problem.
• Compete — enter your project into local and international competitions.

A good fit for tracks such as:

• Natural Production / الإنتاج الطبيعي

What you'll learn

• The acid plus base reaction that makes the fizz (CO2)
• Why bath bombs only react when they hit water
• Measuring and moulding a precise recipe
• Natural colour and scent without harsh chemicals

Extend & innovate

Experiment with colours, embed a little surprise inside, and scale your recipe to gift a whole set. Compare how grain size changes the fizz speed.
