Spoke to a teacher today from my sons' school.
She'd had an idea for the classroom, so roped her dad in to help her prepare the display.
The work was then to be laminated, only half-way through (lots of A3 sheets) one of them crumpled completely inside the laminator.
Teach and dad fiddled and ended up taking the laminator apart to get the sheet out.
Dad then disappeared huffing and puffing. Teach and her mum didn't dare interrupt him for a while, but eventually Teach went to see what dad was doing - only to find him ironing the laminated sheet flat!
End result wasn't too bad by all accounts, lol.
