This is a great example from Evan (Year Two). After a history lesson about the impact of the printing press, Evan was challenged to make a new way of printing. He developed this machine, complete with full instructions - some of these can be seen below. Scroll down to see the amazing results from Evan's printing press!
Stage 1: Get thickish cardboard and two long pieces of string and get a medium size tables and as many pieces of wood for your molds as you need. Get a few drills and carve a pattern or shape.
Stage 2: Pull the string 1 towards you to print on the paper and pull string two towards you once you have printed with string 1 in order to move the paper and then print and move on again.
