No I do not, just that it has to be a novel creation... Hence the difficulty. But I feel like such a device does exist, it does not seem enormously complex..

I'm still trying to figure that out. But I do enjoy talking about it and thinking it through!

Pocket size, no plunger, that was simply an example. The core of the idea here is to just get a circle spinning from pushing something towards the center of the circle, all on one axis.

To reword the question: Take a plunger style spinning top, rotate the plunger 90 degrees and place it inside the spinning top. Now what mechanism will translate the force of pressing down on the plunger to spinning the spinning top. Difficult question I know! lol. Need to think outside the box...

I have been trying to learn Fusion360, I will try my best to provide a 3D sketch. But for the time being, I am thinking of a simple gear system that will spin the outer circle. I just can't piece it fully together in my head.

Correct, everything is to be inside of the circle, no mechanisms outside of the circle. The force must be downwards, or to be more specific, towards the centre of the circle. Here is a crude diagram of something that may work.

It is for a school related project, it's a very open project. I have been trying to think of the mechanism that would allow the desired movements. I'm posting on here to see if there is anyone who has experience and would know off the top of their head how to do it. Thanks.

How did you find PF?: Google search I would like to discuss a simple mechanical system for a project of mine. Here it is if anyone can solve it: Allow me to explain what is required. The circle needs to spin via a downward force represented by the black arrow. The red arrow is the direction...
