I was sorting through a kitchen cupboard the other day and found three half bottles of food colouring from the days when I used to make colourful icing for cakes (mmm, sugar and E numbers).

All three – the faux-primary colours of red, yellow and blue – have gone past the “best before” date on their lids but even not taking that into consideration, I’m unlikely to use them for their intended purpose in the near future since I’ve stopped baking that type of cake and I get my E numbers through large quantities of orange squash these days.

So what else can I use them for? I’m tempted to try them for dying fabric but suspect the colour would just run with water – is that the case? What about other use as other dyes such as in paint?

We’ve had an email from Christina Albertsen:

My colleages and I throw away loads of used staples every day where we work, and I was just wondering if there’s a way of recycling them somehow!

If you have any ideas (apart from buying one of those stapless staplers, which I will be doing) that would be great!

They seem so small but I remember reading in a book a few years ago that a colossal amount of steel is used to make staples. Unfortunately I can’t find the book just at the moment so I can’t find the exact figure but it was a very big number for what seem to be small and insignificant bits of bent metal.

The book recommended using paper clips or treasury tags instead since they’re reusable – and of course there is Christina’s stapleless stapler idea – but aside from that, as Christina asks, are there any ways to recycle (or reuse) staples once they’ve been squished?

When I was a kid, I used to make chains of them for fun but it was fiddly and they had sharp ends so couldn’t be used for much – or could they?

Had an email from Rani:

I’ve saved up the stems of old qtips (cut off the used cotton part) and now have a bunch of little paper sticks.

I’m planning to make a picture frame out of them but would like other more practical ideas before I do something decorative.

I’ve thought about this before too – we try to buy the paper sticked ones but sometimes can only get plastic ones (boo) – at least the paper ones will compost.

So any suggestions for little paper or plastic sticks?
