Wet plaster pours, sets overnight, then fizzes into a bubbling eruption.

🌋 Repeat eruptions: the cast volcano erupts again and again with vinegar and bicarb soda from your pantry
🎨 Own design: paint the set plaster with the six-colour paint strip and brush
🧪 Real chemistry: the acid and base reaction makes the fizz, so kids see cause and effect on the bench
🧰 Ready to go: mould, plaster mix, paint strip, brush, stirrer and instructions are all included
🔇 Quiet play: a soft fizz, no batteries, and a tray on the table is all the setup it needs

The Educator's Note

It turns one afternoon into three skills: mixing plaster to a pourable thickness, painting the cast with a steady brush, then running the eruption as a real experiment.
The eruption can be repeated and changed. Altering the amount of vinegar or bicarb soda lets children test one variable at a time, which is the foundation of the fair-test thinking they meet at school.
Everything needed for the build is in the kit, and the eruption uses pantry staples, so a child can start without a shopping trip and without batteries.

Pour the plaster, wait for it to set, then paint your own desktop volcano and make it erupt with a splash of vinegar and bicarb soda. The mould, plaster and paints are all in the kit, and the eruption ingredients come from your pantry. Made for 8 years and up, with an adult nearby for the plaster and the eruption. Mixing plaster to the right thickness and waiting overnight builds the patience that real experiments ask for.

Also available in a great value bundle

This kit suits children who like to make something and then see what it can do.

8 to 10 year olds who want a science project they can finish themselves, from casting to painting to the eruption
10 to 12 year olds ready to change the amounts and run their own fair tests
Curious kids studying volcanoes or the earth at school, who would like to see a model react
Parents planning a school-holiday or rainy-day activity that takes more than ten minutes and ends in a good fizz

Make it, then watch it erupt

This kit starts with a messy, satisfying job. Kids stir the plaster mix with water, pour it into the mould and then wait. A good cast needs to set properly, usually overnight, and rushing it is the quickest way to learn why scientists keep notes. Once the cast is hard, the paint strip comes out. Six colours and a brush are enough to give the volcano plenty of character, and holding the brush steady around the ridges builds the controlled wrist movement they use for handwriting.

The eruption is the lesson

Pour vinegar and bicarb soda into the crater and the fizz rises and spills down the sides. It is a simple acid and base reaction, and it is easy for a child to repeat and change. What happens with more bicarb? Less vinegar? A drop of food colouring? That kind of testing one change at a time is how science thinking starts, and the volcano gives them a reason to try. At 8 they follow the steps and watch what happens; by 10 or 11 they are planning their own fair tests, changing one amount at a time and recording the result.

Where it fits

This is a school-age project made for children from 8 years, with an adult nearby for the plaster mixing and the eruption. It works well as a rainy-day or school-holiday activity, one child alone or a pair sharing the painting. Do the plaster and eruptions on a tray, an old tablecloth or outside on the grass, as wet plaster and fizzing vinegar are both messy. The finished volcano is small enough to sit on a desk or shelf between eruptions.
