At “Maker Faire Africa”, a craft fair recently held in Lagos, blogger White African
met a very creative young man. At just 15 years of age, Odo Gerald builds miniature construction engines powered with water syringes that apply hydraulic pressure or with motorbike batteries.
This teenage inventor has worked on these toys for the past four months. He has already built a mechanical digger and a garbage truck with pieces of plywood. His next project: a small helicopter that can fly in the air for several seconds.
