I was struggling to come up with more machines so I started to think about what small tasks I do during the day. I was clearly uninspired and didn't really come up with anything. A quick chat with Charlotte though resulted in us coming up with a few ideas for stupid inventions. If you can't read the list it says:
Finger nail spoons, cutlery belts, eyebrow hair dryers, envelope tongue, window wipers for glasses (although I think they already exist?), double hook hangers, poppers (buttons not drugs) disguised as laces, wearable armpit sprays, hairbrushes fitted to pillows/doorframes.
Charlotte's going to visualise some of these and they should be on her blog.
