This is usually the other way around – we usually suggest things that can be used to insulate water pipes – but I saw some foam water pipe lagging on the road today while walking the dog. I imagine it had blown off a nearby skip or been taken off by kids (because reuse #1: they’re great for sword fights) but either way: yoink!

Given the rain of the last 24 hrs, they’re a bit wet but since they’re plasticky foam, I imagine they’ll dry fine. We’ll probably use them for actual pipe lagging as we’ve just had some new pipe work put in – but if we were already insulated, what else could we use them for?

We’ve had an email from Rowena asking about reuses for foam egg boxes:

I’ve seen all the ideas for paper egg boxes but I get plastic ones sometimes. I can’t even compost them!! What can I do?

The first suggestion I have is possibly a little unhelpful but “reduce” – don’t get the plastic ones any more. As I said, that’s probably a little unhelpful because I’m guessing that you wouldn’t get them if you had a choice but still, it’s always worth reducing if you can.

One advantage foam boxes have over cardboard ones is that they’re not so easily damaged when they get wet so they’re better for certain reuses – I remember using them as colour palette while painting as a kid. They can also be reused many times for their intended purpose – offer them to chicken-owning friends or take them with you to use when you buy eggs from somewhere that sells them loose (such as certain farmers’ market stalls or markets in general).

Any other suggestions specifically for foam ones?

We’ve had an email from Petra:

From a party project, we have left two big foam “things” with holes in it. See the picture included. They measure 108 by 47 by 18 (in centimeters). The holes are large enough to hold a winebottle. But the foam is quite soft, so it’s not safe enough to make it into a hanging wine rack.

I thought about it being playing items for the kids in the garden, but any better ideas are more than welcome.

The bright colour, softness and chunkiness make them feel very much like something for kids – one of those things that if we’d had it as a kids, we’d have come up with a thousand different play uses for it. If you have a few, another kid-related thing might be to string them up as hanging dividers in a bedroom – such as between the sleeping area and the playing area, or to give kids a little privacy/sense of their own space in a shared room.

Aside from that, if you could find boxes big enough to hold them (under bed storage boxes maybe?), they might be useful for keeping glasses or bottles safe during a house move (if you’re not moving, someone on Freecycle probably will be!).

They also could be useful in the garden if you’re growing a lot of seedlings – holding plant pots upright when they start to get a bit top heavy or if it’s windy.

Any other suggestions?

We’ve had an email from Jess:

What can I do with a baby changing mat made from foam?

Like with all baby stuff, my first thought is to pass it on if you can – they’re usually used for such a short period of time that they tend to stay in pretty good condition. Pass it on through a baby group, a charity shop, Freecycle/Freegle or something like an NCT nearly new sale.

Aside from that, changing mats are just flat wipe-clean foam cushions so could be useful in lots of situations. If the covering is completely sealed & waterproof, a small child might prefer to sit on it in the bath rather than the hard surface of the bath itself. If the covering is punctured or just water resistant, it’d still be splash-proof, so you could fold in half and use it as a kneeling mat for you while bathing Junior, or it could be used as a bathmat when they get out. Similar, it would be great as a kneeling mat/cushion in the garden.

Any other suggestions?

We’ve had an email from Hannah:

What can I do with old flip flops?

I’m presuming Hannah means the cheap foam ones that are omnipresent in the summer but sadly disappear into the dark, dusty backs of cupboards as soon as autumn arrives, never to re-emerge.

Because, toe-thong aside, they’re pretty much just foam shapes, a lot of the suggestions for foam drink holders and foam swim float will apply here too such as floor protectors under furniture legs, cut up/carved for foam stamps, or used as knitwear blocking boards or boards for macrame. If they’re not too, um, footy, they could maybe also be used as a fun noticeboard – a few pairs walking along the wall would be super-fun :)

Any other suggestions?
