#358: Carol corral

Today’s invention is a metal fence for schools and playgrounds which is also a musical instrument.

Think of this as a vertical xylophone. Each metal upright (or tubular bell) would be moored, so as to retain the children, but free to vibrate when struck.


The vertical spacing of the moorings for each ‘rail’ would be movable (by an adult with a key) so as to create sections of the fence arrayed like the notes on a xylophone -and other sections which could play a tune as a child runs past, brushing them with a stick.
