4M Green Science – Eco-Tech Bulb

The Green Science Eco-Tech Bulb by 4M is a hands-on renewable energy kit that lets children build a working LED lamp powered by gravity or manual cranking. Once assembled and attached to a recycled bottle, the lamp lights up using nothing more than kinetic energy—no batteries required.

This clever eco-engineering project introduces children to sustainable power, mechanical energy and electricity generation. Kids learn how movement can be transformed into light while developing practical STEM skills through assembly and experimentation.

Suitable for ages 5 years and above.
