DOT BOX SOLUTION
updated 20th December 2014
The DOT BOX solved.
You might like a pair of Compasses
You might like a Polar Planimeter
You might like a Cyclotron
But you do not need any external tools to solve the DOT-BOX.
SOLUTION
To solve: -
1) The box is pushed lid uppermost into the plinth.
2) Anti-centrifugal or Centripetal force is applied. This will move the loose radial non-magnetic pins towards the centre thus unlocking the lid.
3) Carefully remove the box from the plinth and place it on the table being careful not to jog the pins.
4) Holding the box steady on the table, turn the plinth upside down and push it down over the box lid. Now when you lift it up again it will pull the lid off.
We expect that you are baffled by the "apply anti-centrifugal force" bit. So here are some more thoughts: -
Think: Why is the plinth base circular and not for example square?
Think: Why do we not recommend trying to solve it on a carpet or duvet?
We hope we have now given you enough hints to enable you to work out the solution.

If you are still stuck take a one pound coin and spin it on the table and see if it falls heads up or tails down.
This puzzle really is designed to work on a completely new principal and we really do want you to explain it to us.
For an even more detailed solution wait for the IPP34 book
or watch for this paragraph to be updated again
or, in desperation, feel free to email us.
PROBLEMS
If you think your DOT BOX is not working properly:
Check that the lid is pushed fully home (down) and jiggle the box horizontally to ensure all parts are loose. Email for further help.
ALTERNATE USES
You can put the box in the plinth upside down and use it as a sculptural paperweight
and while away your working day by arranging paper-clips on top of it.
But really you should use it to baffle you friends with science.
