The final product of this section will be an "extraordinary" artefact, created by combining creativity, imagination and ingenuity. In order to carry out this task we will need to activate our previous knowledge regarding different types of artefacts. In addition, the objectives, methodology and resources that we will use in the next three sessions will be established. The creation of the artefact will involve the revelation of the third, and final, digit of the key to the padlock and, therefore, its opening.
