| Short description | One of the experiments for children The most fun is to make a chemical garden. It consists of the almost instantaneous crystallisation of metallic salts (copper sulphate, magnesium sulphate, ...). The name chemical garden comes from the fact that the result of what you get resembles a coral garden, or even an aquarium with plants. |
WHAT IS A CHEMICAL GARDEN
A chemical garden is a garden that is made from chemical compounds, specifically metallic salts. The powdered salts are introduced into a solution of sodium silicate and begin to grow upwards, creating a real garden of what looks like corals. Below you can see the detailed step-by-step of this fun experiment.
MATERIALS FOR THE EXPERIMENT
The materials used are:
- Sodium silicate.
- Copper sulphate pentahydrate.
- Nickel sulphate
- Iron sulphate
- Potassium sulphate
You can get all these elements at Alquera.com
STEP-BY-STEP EXPERIMENT
Step 1
Take a container and add 1/3 of sodium silicate and 2/3 of water.
Step 2
Gradually introduce the salts. Start in small proportions, and add more salts later if necessary. Attention! Use hand protection for this step.
Step 3
Wait a few minutes and watch the crystals grow. You will see bubbles forming upwards, above each of the bubbles is where the garden grows.

CHILDREN'S REACTION TO THE EXPERIMENT
I have tried to do it with the products that you tell me, but it doesn't work. Any idea of the cause? I use tap water
Hello, do you use sodium silicate and metallic sulphates? What materials have you used?
