Runs with hot water ... kit from 14 years
The metal wire "remembers" another shape when it gets hot. Submerged in hot water, this kinetic energy can be gained, as this small kit impressively proves!
Dimensions: 10cmx10cmx10cm

ATTENTION! For children under 3 years not suitable. Choking because small parts can be swallowed or inhaled.

Warning: To be used under the direct supervision of an adult
