He used a paper cardboard and other paper materials to develop the entire excavator. He developed the hydraulic system with dip tubes usually found in aerosol cans. The used syringes were used to apply force to the water(serving as hydraulic oil) inside the dip tubes to effect movement.
If this young boy who has not even completed junior high school has got this great talent to develop such a great engineering prototype, then Ghana we have a great future.
Government must get serious and start hunting for these young guys who are mostly hiding in the rural communities.
