Budding astrophysicist Luyanda Mazwi has a cool idea: a pavement ‘fridge’ that helps vegetables and fruit last longer. The gadget is environmentally friendly and could change lives.
In a small church in the Johannesburg suburb of Brixton, a rowdy crowd is singing along to Freshly Ground’s Doo Be Doo as it is performed by a small, enthusiastic choir.
It is the last performance of an evening of music and poetry that has been organised by Luyanda Mazwi, an astrophysics master’s student at the University of Johannesburg. He has planned and funded the whole night for one purpose: to ask if anyone has a 3D printer he can borrow.
