#1527: PuddlePointers

Every time it rains, as cars drive past me I get splashed by the bow-wave they create when I’m standing waiting to cross the road.

Today’s invention is biodegradable coloured particles (probably made in the form of cork discs).

Kind hearted people would throw a few dozen of these into any nasty kerbside puddles they saw.

When a car passes, it blasts water and particles onto the pavement. The water washes away but the particles remain.

Subsequent pedestrians can see the area affected by previous car splashes and avoid standing within the affected area.
