😅😅 As I graduate, allow me gist you of my university days. We were asked to make ...

... a working carton model or prototype of a machine we had pre-selected. Mine was a water borehole drilling machine and there you have it.

The syringe is meant to push down the drilling tool (modelled with a nail). The drilling tool is spinned by a little electric motor gotten from a dvd.

It actually drilled through a styrofoam when I connected it to a 12v UPS battery.😏

Wahdahya think?😁😁 Cool or not
