The STEMerica project concluded on 12 May 2023, but its activities continue. We spent this past sunny weekend outdoors testing our Gladius Mini S submarine on Lake Petnja in Brod-Posavina County (Sibinj Municipality). At the lake we prepared test runs for the demonstration sessions at the festival run by the INNCRO-IT association, whose date is drawing near. This time the dive went to a maximum depth of 3.75 m with a surface water temperature of 21.3°C. Because of last week’s rainfall the water was murky and it was hard to find a varied animal world in it. You can find out more about this at the festival! Visit Lake Petnja on 20 June 2023 and see what we and our partners have in store! The project was co-financed by the European Union from the European Social Fund through the call „Strengthening the capacities of civil society organisations for the popularisation of STEM“. #fablabhrvatska #inncroit
