Previously, we posted about Katie’s Binary Nail varnish tutorial video, and how you can use glitter (
1) and no glitter (
0) to encode binary messages in your nail varnish. We also posted an accompanying puzzle, stated as:
Suppose I want to paint my nails on one hand differently every day for a month – so I need to use all 31 combinations involving glitter. Assuming that a nail painted with plain varnish can have glitter added, but a nail with glitter needs to be nail-varnish-removed before it can become a plain nail again, what order do I apply the different combinations so that you minimise the amount of nail varnish remover I’ll need to use?
Here’s our take on the solution.
I’ve just posted my latest YouTube video, in which I explain how to use binary numbers to jazz up your nail varnish:
Alongside this video, I also have an associated puzzle for you to think about.
One of the many jobs we’re gradually getting round to in our new flat is that of tiling a small section of the kitchen surface, which for some reason was left blank by the original builders and all intervening owners. And what better thing to tile it with than binary numbers?
The turnout this month was slightly lower than usual, but many of our regulars were there and we had the chance to have some good discussions and really get into things.
