And now - the Licaspitar!

My grandchildren asked me what I wanted for my 75th birthday. I said some liquorice would be nice.

Better than that they invented and built the Licorspitar. You insert the liquorice into the rectangular hole at the back and crank the handle. It gets carried along a conveyor belt and dropped onto a slope. It then rolls at speed out of the mouth.

How can we monetise this invention?
