Our products inspire kids and families to think deeper, play longer, and figure stuff out.
With 200+ years of science publishing behind us, we've helped shape the STEM category worldwide. That heritage guides every product decision, from content development to quality standards.
We solve engineering problems most toy companies wouldn't attempt. GeckoBot climbs glass, Gecko Run builds marble runs on walls, and the Mega Cyborg Hand, a wearable hydraulic exoskeleton, was the #1-selling science toy in the US in 2025 (Circana).
We turn complex science and technology into fun, hands-on experiences for kids and families. From crystal growing to advanced robotics, we make the challenging feel approachable and the approachable feel exciting.
