Science is everywhere. But, can it be found in the fantastic imaginary of fairy tales? In the enchanted forest, in Hansel and Gretel´s chocolate house, in the magic mirror of the Wicked Witch or in a beanstalk that grows endlessly until it touches the nose of a giant?

ONCE UPON A TIME is an interactive exhibition of science and technology, in an environment absolutely magical of fairy tales focuses on ten children's stories, that are true classics of children´s literature, and challenges visitors with more than 30 interactive exhibits.

The exhibition was created by the Pavilion of Knowledge - Ciência Viva Science Centre in collaboration with national scientific institutions and exploits phenomena and concepts of social and natural sciences such as Physics, Chemistry, Mathematics, Geology and Biology.

This exhibition is for all those who have read, heard, or dreamt of fairy tales. Nobody is left out: children, adults, everyone can come, explore and discover, and is also accessible to people with special needs.
