There is a small hollow pipe that I have which is the size of your thumb...I would like to somehow sense where someone squeezes the pipe and if the pipe is being squeezed then I would like a random stick or piece of wire to move...I know the description is very vague but this is just what it is
Okay I decided to include a diagram...So basically when some kind of button is pressed a wire pops out under. I am planning or thinking of building some kind of spring triggered thing here...any idea?
I dont know what the cheapest method would be to sense this force applied or how to move this wire up at time of force.
I think I could embedd some surface with a button underneath to sense the squeeze force....if I do this how could I raise the wire up? I dont know if motor is the most efficient choice here..
Ya you could use a pushbutton underneath if you want to just detect if there is actually a force that would be the cheapest way . I'm also sure there are sensors out there that can detect force for example.Embedded Force Sensors | Tekscan
To rise the wire up a servo is easier to handle and program.
As for the sensor: I cannot imagine what exactly you wanna achieve but to me it sounds like a flex sensor may do the job. The more you're bending it the higher your signal is.

I saw those but too expensive...I figured a simple spring lever adjustment will do the job just fine.
Is the tube allowed to deflect? This sounds like the sort of thing that could potentially be implemented as a purely mechanical solution, with a little thought.
