What’s a Monster Mouth? Monster Mouths are playful, air-powered creatures that come alive through pneumatics - pistons, cylinders, and air pressure.
This playful engineering set has ten individually packaged, ready-to-build 1:1 kits for learners to make - and keep! It's perfect for small group classes, STEM activity stations, or make-and-take projects for special events.
It's a perfect 20- to 40-minute screen-free activity for grades K - 3, with extensions available in our educator guides. Monster Mouths are popular family engagement or multi-session experiences for PK / TK / K learners.
Learners design and build a creature with features that move using a pneumatic system. By experimenting with pistons, cylinders, and push-pull forces, they explore movement, and the invisible properties of air. Each build combines science and imagination, giving learners the freedom to craft their creature features and bring them to life while problem-solving along the way.
