How can you check out the stabletable? Where can you get one? You should have published Mr. Gordon's web site.

Surely it's worth more as a promotional item that large breweries can buy in bulk, heavily brand and place around their establishments, so that people take them home as free advertising?

Or in an IKEA grab bin as an advertising loss leader? IMO it's more a novelty product than a commercial must-have

When you've all finished debating your angles and rotational symmetry, you don't need a mathematician to realise that more often that not, it's the floor that's uneven thus causing the 'wobble'. Stabletable enables firmness in any position - so to speak of course!

Nicola, Windsor, Berks,

so these so-called 'experts'can get it wrong - good luck Andrew!

Sales of £500'00 doesn't mean a £500'000 profit...

Al, London,

Isn't he gorgeous...

Alan Jones, London, UK

Okay, I'm going to jump onto the bandwagon! Here are my upcoming million pound inventions:

STABLECable

Cable TV that doesn't freeze, take 5 minutes to load that little programme guide at the bottom of the screen & manages to retain decent Sky channels.

STABLELabel

Some sort of small piece of paper with some semi-adhesive glue on one side, so I can leave little notes explaining the function of common household items to my children when I go on holiday.

STABLEStable

Not quite sure how this one works, but it's going to be big. Real big.

Success in business is about selling product. Nothing more or less. To suggest that success in business is related to talent and hard work is clearly naive.

The ever so smug 'Dragons', who were presumably chosen for their obvious physical shortcomings, are as fine an example of this general propostion as ever there was.

JC, London,

Ian - you clearly haven't a clue about maths! Think about what you suggested and congratulate the man on a great idea!

David Hartley, London, UK

As anybody living in the real world knows, trying to work on a square or rectangular desk that has been rotated at an awkward angle simply to rectify a wobble is often extremely impractical.

Perhaps Ian would care to rearrange the workstations in my small offices so they stop wobbling?

Paul, Plymouth, UK

Ah, Mr Boyce, it is the rotational symmetry that helps us, as we know that after a 1/4 turn, the leg that was in the air is now on the floor, and the next leg around is now in the air instead.

Obviously, during that quarter turn, the first leg touched down, and, unless the floor is out by several feet, it always does this before the other leg lifts off.

John, London,

Good to see that simple but very good ideas, can still make it in business - in all of these online, need it now times.... Hopefully he can make a mark internationally! And, as a trusted user of Stabletable, the amount of red-wine staines on my chino trousers have been dramatically reduced.

Espen Vestli, Burnham, Berks, UK

As any mathematician could tell you, Ian Kemmish is mistaken in saying for ant table, there will always be a point at which all four feet touch the ground. Imagine three legs one foot long and one leg two foot long.

Kenneth Gray, London,

Ian - You are clearly not a mathematician!

Brian Jones, Huddersfield,

I've got to back Richard up - how on earth would rotating a rectangular table 180 degrees make any difference at all?! And the same for a square table? You aren't changing anything!
Think about it...

Rich, Newmarket,

Interesting technique of rotating the table Ian.. but I like my table in the position where I choose it to be, not just the angle where it's level. Therefore you have to use a device of some sort under the legs.

Well done Andrew!

Chris, Birmingham, UK

All I can say is well done mate!! You were laughed off the Den and are now nearly a millionare, good on you :)

Tricia, Boston, Lincs

1: It's three points to define a plane not four. The fourth leg causes the issue.

2: Most furniture is rotationally symmetrical. Turning it makes no difference.

Richard Boyce, HAYWARDS HEATH, UK

Ian - it's all very well rotating your table until all four feet touch the ground, and wobble is eliminated, but I'm sure "any mathematician" can't guarantee that the resulting position will ensure a horizontal table-top!

Paul, New Forest, UK

As any mathematician knows, a wobbly table can be made stable simply by rotating it. For a square table you may need to rotate it by up to 90º, for a rectangular table you may need to rotate it by up to 180º, but no matter how uneven the ground, there will always be a point at which all four feet are in contact with it.

This usually takes me less than ten seconds. My record for fiddling with spacers, shims or recycled sash window wedges was five minutes before I gave up in disgust....

As for Dragons' Den, the dragons usually only laugh if the victim is asking for substantially more than the half million less costs this business has so far yielded. It's a pity you don't remind us how much he asked for.

Ian Kemmish, Biggleswade, UK

Andrew's innovation is simple and effective. I see it as ideal for stabilizing furniture which is regularly moved around. He left me a sample when he stayed with me in Australia. Full marks to him for his persistance

Vic Walker, Nowra, Australia
