What: rear view glasses, found as part of the Mission during Kid 7’s spy-themed birthday party. And a message in mirror writing, to solve using the glasses.
How: I looked for rear view glasses online but couldn’t find any cheap enough to order in party quantities. Kid 6 had a pair from a school book club set, and I’d made some once as a kids activity at a science museum. So I knew the rough idea. I ended up ordering a bunch of kid-sized sunglasses from an online party goods store, and a bunch of small craft mirrors from a big box craft store, and assembling them myself. I did consider getting the kids to do it, but thought it might be a bit slow/tricky for a group of six and seven year olds to manage themselves. Maybe nine to eleven year olds would have been fine with it. The problem with self-assembly is that the bits don’t quite match up in size and shape – the glasses have too much curve in them (you want them to be quite flat rather than following the line of a face), the mirrors are too big to fit inside the frame and at the same time too small to see effectively in – that sort of thing. I tried superglue but couldn’t get the mirrors to stick well enough to the frames, so ended up using double-sided sticky tape. Which was mostly a temporary solution, but held together well enough to get through the party.
The kids found the glasses all ready for them in a box in the bathroom, and gleefully put them on. I’ve found with these that they are really tricky to use the first time, and then the second time it’s a lot easier. It takes a little practice working out how to focus on the mirror and make sense of what you’re seeing, and then how to turn your head so you can choose what to look at. The kids had fun trying them out. Some got it, some didn’t, but the idea was Super Cool (and it was sunglasses which are automatically cool) so that was all right then.
Also in the bathroom, on the mirror, was this big message, in code. Well, in mirror writing. Which doesn’t seem like a tricky code, but given that several of the kids are still working through the first hundred sight words list and can’t immediately recognise words when they see them, and some are not reliable at identifying mirrored and flipped letters like b/d/p/q, mirror writing *was* tricky. I made it a little trickier by breaking up the words and using multiple colours so that even the kids who would normally recognise the words on sight didn’t just immediately know what the message was, and that seemed to even up the speed a bit or at least slow down the faster ones. Trying to read the message with the glasses was a bit tricky for the kids, but being in the bathroom there was another option. Several of the cabinets had mirrored doors, and there’s a mirror on the bathroom door, and if you move the various mirrors around you could get it so the letters were all the right way without having to use the glasses. The message was written with some pens I found that are specifically for use on mirrors, glass and bathtubs and the like. They go on like oil pastels and wash off easily.
