Inspiring the next generation of engineers

The whole chocolate factory is the classroom

Every session follows a chocolate bar through the full manufacturing process, from cocoa bean to wrapper, so STEM stops being a subject and becomes something children can see, touch and taste.

Science

Melting, tempering and crystallisation, and why good chocolate snaps.

Technology

Production tracked live on Siemens Insights cloud software, just like in industry.

Engineering

See real factory machinery mould, cool and finish every bar, up close.

Maths

Temperatures, timings and weights that all have to add up to the perfect bar.

School visits also cover cocoa farming, sustainability and fair trade, and finish with pupils designing and branding their own chocolate product.
