I decided to do improve an idea I had when we were doing the extraordinary books project... 'Its a book that is not there'.

 Fed up with not only being asked for ID but also forgetting my ID and recently losing it I decided wouldn't life be easier if hwen you were 18 you had a small tatoo done and we just showed this when required!! Yes I have thought that if you were not 18 then you could do one yourself, it could have special ink that you can scan with a scanner.. at least you wouldn't forget or lose your ID!
