Paper engineering

D has the same teacher as C had last year. It turns out C did lots of paper engineering too but he didn't love it as much as D and so we didn't see it. D is filling my kitchen with paper boxes containing paper spring jack in a box and paper aeroplanes. The paper aeroplanes are now 'models' he claims - I'm sure this is a rouse to make sure I don't throw them away!
He's now making them multicoloured and stacking them before launching them from the railings at the top of the stairs.
