Good and not so good has come out of re-assembling the shuttering around the concrete and ping pong balls:  Good in that the cracks seem to be less evident and the concrete seems more solid.

Good in that the the mix I used looks as if it might take a polish – given the shiny surface on the bits which filled up the cut portions of balls.

Good that the hexagon shape remained regular…..

But only at the bottom!  The top sheared two screws and opened up – the wonders of water and the forces of nature!

What next?  Well, the gaps are very narrow between the balls and I fear that if I try and dig the balls out bit by bit the whole thing will all fall apart [one bit at the top has already broken off].  So the plan is to burn them out [they might melt out which would help lessen the smoke].  However, if I try that now, the water in the concrete is likely to boil and blow the whole lot up.  I shall just have to wait until it dries out more – I shall start again on this project next term!
