On November 30, 2012 the Experience Workshop’s Zometool Team joined the Celebrational Closing Gala of the Hungarian Mathematics Contest in the László Papp Stadium, Budapest. The successful contest – with more than 6000 participants this year – was initiated by Tibor Hervay and Krisztina Hervay teachers. The Experience Workshop conducted a Zometool Giant Building workshop with the participation of the children and their teachers and families. The participants built up a large-scale Zometool model of the Atomium from Brussels, the European symbol of science, art and education, with the leadership of Ildikó Szabó.
