Harry Potter - Floating Thestral. A chained Thestral that wants to rise into the air - creating an optical illusion that needs to be built! Due to the effect of tensile strength, the Hippogriff appears to float in the air. This is a playful experience with a surprise effect, offering lots of fun in building and inventing solutions and game scenarios with the famous Harry Potter character. By assembling the various components, children can bring exciting scenarios to life through their constructions, giving shape to their ideas with their own hands. The fantasy world of Harry Potter comes alive in a model to be assembled, allowing for the discovery of a new construction principle: Tensegrity. When attaching the chains to the structure that supports the Thestral, children learn how tension creates structural integrity, making the Hippogriff seem to float in the air.
