OK, so unless you've got a really strange craving, most of us wouldn't eat Corn Flour (Cornstarch for our US friends). Nevertheless, this is one of the most cool things to play with, and you probably have it in your kitchen. It's a great thing to do with young kids, but if you're anything like our MD, you might well find it intriguing yourself.
What's a Typewriter?
As part of our visit to IBM for the Raspberry Pi day we had a tour of IBM's museum. During the tour we were shown some of IBM's typewriters and after a long (but concise) explanation of the development of the typewriter, one of the kids asked what did these 'typewriter' things do? It never struck the rest of us adults that most of the children would never have seen one of these before.
I suspect the adults enjoyed this bit of the tour more than the children, reminiscing about days when 'laptops' could break your knee caps if you actually tried to put them on your lap. The history of the site was impressive as well, with Hursley House being used for the development of the Spitfire during the war.
