Building the electronic sensor components from scratch, Gerard Marull Paretas, Sergi Saballs Vila, Marta Gasull Morcillo and Jaume Puigmiquel Casamort managed to send their heavy duty £43 latex balloon to the edge of space and take readings of its ascent.
Created by the four students under the guidance of teacher Jordi Fanals Oriol, the budding scientists, all aged 18-19, followed the progress of their balloon using high tech sensors communicating with Google Earth.
