craft yourself some army surplus

I was just researching some less plans for political stuff and I came across this craft activity. Yes, it's how to make your own gas masks by the John Curtin Prime Ministerial library. There's a number of lesson plans on the site which include 'craft activites'. Naturally I clicked on it, and clearly this fun gas mask was the only one they'd thought of stemming from Curtin's time in office.
