Neither glue nor magnetic attraction is involved here, nor is it a bluff - what seems so amazingly magical is based on pure physics. Only a little skill and dexterity are required to be able to prove their laws in the BluffBlock experiment.

Three building blocks in different shapes, numerous possible combinations: Which figure will successfully defy gravity? To find out, an accompanying booklet with eight given figures that can be replicated, helps you over the first experimental hurdle. And this, as quickly becomes apparent, in highly varying degrees of difficulty. Of course, you can also design your own constructive combinations of the three building blocks, always remains the game with the possibilities surprising.

What keeps the seemingly impossible to replicate figures actually in balance? The puzzle's solution: Inside each BluffBlock is a movable steel weight that can be shifted by gently pivoting the brick. Even the slightest shift of this weight means a shift in the center of gravity - and already a cylinder segment stands recklessly on its outermost edge, already an arc can lead into empty space without falling into the abyss.

Highest care in the processing of maple wood is necessary to "move" the BluffBlocks to this amazing behavior. Emma Brix, an industrial designer in her own right and the developer of the BluffBlocks, has the building blocks made in the Erzgebirge mountains, where the knowledge of generations keeps the traditional wood craft alive. The inner track, in which the steel weights can move, is milled out of the BluffBlocks to the millimeter, the maple wood is carefully sanded smooth, and the two halves of a building block are precisely put together. In addition to the pleasantly natural haptic experience provided by the sanded, oiled maple wood, the BluffBlocks also challenge your visual perception and cognitive agility: Can the building block still be moved a tiny bit - or is the collapse of your structure imminent?
It remains amazing - even without being a bluff.
