Mark Making Device

I FINALLY finished my device...It was quite difficult to make. At first it was just going to be the slinky and the fan attached to it then I would dip the blades in the ink then turn the fan on....but no that idea didn't work out. So Then I decided to drip the ink in behind the blades...it was really cool!!! So I went with it...but I failed to see the slight technical difficulty in this idea. How am I going to drip the ink into the device when the whole object is moving???  Now this was a major problem and took awhile to figure out. It ends up that I had to attach a tube that ran up the middle of the slinky from the top all the way down to the blades...now for the next problem the tube obstructed the slinkys movement. I had to cut the tube to the exact length of when the slinky would be at its maximum height and then have it run on the outside of the slinky and I attached it to a wooden rod then attached the slinky to the rod.  So many problems for one device, but there is more...now I was having difficulty getting the ink into the tube without spilling...so I was searching my room and i found mini little paint cups with lids!! I stabbed a hole in the bottom of the container and attached it to the tube and the wooden rod. Well i think that was all the problems I've had so far...

So I began testing out my object... Most of the marks are similar till I figured out that I could let the device drop completely to the paper and allow the blades of the fan hit the paper, created a really neat effect!! I stuck with that idea for a while, testing it out trying to get different effects with the same method. 

I was trying to close the lid to the paint cup at the top of my device after putting more paint and water into it, when i noticed by opening and closing the paint cup increased/decreased the air pressure within the tube causing more/less paint to come out at one time. New method!! So now i tested out this idea, getting a wider variety in the amount of paint released giving greater value to my sketches.

curious how it would look with the tape
