We hear a lot these days about e-learning and gamification.
Today’s invention incorporates both these elements into a system to help students.
A laptop DVD drive would be fitted with a shallow cylindrical box, full of flat circular sweets (these sweets would be arranged in a spiral and pressed towards a small aperture in the box using a spring, in a similar way to rounds in a drum magazine).
On completion of some on-screen task, the drive would rotate the box so that the aperture in its base arrived at a specified location and then the drive would be opened.
Having arranged for the aperture to be unobstructed by the drive base, this would allow a student working on the machine to catch a sweet as it falls out of the box’s underside.
The drive would be closed and a new task begun.
