For the final we wanted to used cylinders for connection but didn’t do it as  we thought that using the stick was enough. but it wasn’t. so I think one improvement we have to make is that we could use a cylinder to connect the two gears together instead.

The problem with the bicycle gear concept was that the sticks did not stick properly no matter how hard we tried so i think that maybe instead of using glue, we could us the wooden stick to pierce through the stopper so that it won’t succumb under weight.

This is one of our initial sketches to make a rotating object that pierces through the paper.

Initially we wanted to make a bird that pierces through the paper, tearing it.

the video of the final. this was after the sticks spoilt so it’s not exactly working.

Ps sorry for uploading this so late, I had problems with the upload of pictures and some pictures i don’t really know for what reason, would not upload at all. so these pictures are only a fraction of what I want to show.

Over the holidays Ill continue working on it and making a better model.
