The Mystery House Raiatea invites you through a guided tour to discover more than 20 strange workshops that will put your senses to the test. Inspired by the mythical “Gravity Hills”, which, due to the absence of a visual horizon, give the illusion of seeing a road going up, when in reality it is going down. Some examples of the workshops presented are: – La Boussole Folle: a magnetic compass that disorients itself! – Foucault’s Pendulum: a pendulum that stops by itself! – The Infinite Arrow: an arrow that always points in the same direction! – The Reverse Slope: water or ping pong ball going up the slope! Our best guide is also the instigator of the project. Passionate about optical games and facts not explained a priori, Gérard will take you on a merry-go-round of illusions and change your point of view forever. With a good-natured mood and a desire to share his vision of bizarre things, Gérard will make you have a great time.
