On the 26.8.20 we did a really cool experiment called AUTOMATA , this is all you need! trust me its really cool.
* Lot's of cardboard
* A hot glue gun
* Skewers
* A printer or pens and paper.
First you get a cardboard box and then you make some cams ( if you don't know what cams are they have many shapes like heart shape, oval shape, circle shape and many more )
You pick one of them and put it through the skewer and then you put it through the cardboard box.
Then do the same thing but make a circle cam at the top and then attach it to the drawing or a printing, and then your finished.
its So much fun and super easy.
