Standing on the left with this team that made it to the 2016 competition final is their local MP Naz Shah. Hydro-lock want to address the problem of drought and water wastage in agriculture. Their Big Idea was to enrich soil with the chemical contained within nappies to increase its water storage capacity. This innovative solution was thought of on their Big Ideas Day and the team worked tirelessly for the next three months to develop their idea for the 2015/16 S4TP competition.
Hydro-lock worked with their science teacher (previously a chemist) to discover the active chemical within nappy fillings was called sodium polyacrylate. They then contacted BASF who produce the chemical to find out more about it and its safety.
