Building Enigma Machines

Our year 10s headed to Falinge Park in Rochdale, to participate in their final Bletchley Park workshop. This was particularly special because they were able to build their own Enigma Machine and use it to encrypt words.

To inspire them, students viewed a demonstration on an original Enigma machine. The Enigma machine was developed privately in Germany in 1923 for banking. It was able to provide substitution ciphers with 159 quintillion different possible key settings!

The students were armed with three Pringle tubes, glue, sticky tape, scissors and printed strips of paper to create the machine, along with a precise set of instructions. It was a simple but highly effective way of students being able to simulate how the real machine worked.
