The card house illusion

The card house illusion involves constructing a delicate structure from playing cards that appears to be floating or unbalanced. It relies on careful balance, precise placement, and understanding of the cards’ center of gravity. The illusion tricks the eye into perceiving instability or defying gravity, when in fact the structure is stabilized through subtle alignment and force distribution. The illusion demonstrates how perception can be influenced by visual cues, making something seem impossible or improbable even though it is meticulously and stably built through skill and physics.
