    I saw one of those tension toys where one bit of metal ‘floats’ above the other simply by the tension in the string.

    Looked fun but wondered if I could do something useful like make a table. I have a nice bit of wood that I am hoping to collect at the weekend but thought I had better knock up a prototype first to check if it was possible / practical.

    An off cut of timber, a bit of scrap ply, some garden wire and a few spare washers and I have a working prototype.

    I might even do a “Are you bored enough to watch me tie some wood together” video of the real thing

    Weirdly I saw one of those earlier today on faceagram or somewhere.

    Something like this. Wouldn’t want to put me Estrella on it I don’t think.

    Those are the types of thing I saw. I just wondered if I could make a usable table and it looks like I can. I might even try for a seat if I get bold.

    What do they say about your username?

    Re Lego, there’s a few on rebrickable

    This might be a good one to model a table on:

    Oh, I’ve got it now! The tension strings are counteracting rotation, not gravity.

    This is quite a good video that shows how it works:

    What could possibly go wrong

    Tension chair, glass tension Coffee table and an angle grinder somewhere in there for good measure?

    Oh yes, I’d watch that. no don’t do it, won’t somebody think of the children.

    won’t somebody think of the children.

    After some of the ways it could go wrong having children maybe out of the question.

    WE’ve got a couple of these mde in the first few weeks of lockdown. ONly issues are that they are solid in terms of downwards force, but take relatively little to ‘twist’ the top so the whole thing collapses. There are square models rather than the more common triangular ones that are more stable I think. The other issue is use string that doesn’t stretch over time – ours has become much looser with playing and general stretching (oh err missus)
