The children have discovered a phenomenon in the centre of our Nelson Labyrinth!  

Full of delight, clapping in joy and listening for the Labyrinths’ response, they watch the eyes of near-by adults get bigger when their claps echo back!  The high-pitched squeaky echo is subtle, but very distinct.  It sounds the loudest when the clap is made over the very centre brick. 

And it remains a mystery.

SCIENTIFIC EXPLANATION?

We’re not the only one.
