GLOW IN THE DARK PAINT

Would glow-in-the-dark paint,

help pre­vent tram­pers get­ting lost on New Zealand bush walks? Gil­bert van Reenan felt dif­fer­ently in this let­ter to the edi­tor: ‘‘I can’t be­lieve that you would even dream of fil­ing this story about the drongo Is­raeli desert sur­vivor. ‘‘ I don’t know if you’ve been on the track but you can see it on Google Earth thru the tree canopy. ‘‘Some­one de­lib­er­ately leaves a track you can drive a car on and then wants sig­nage to show her how to get back? ‘‘Why couldn’t you be more crit­i­cal and ob­jec­tive about her stu­pid­ity and ut­ter in­com­pe­tence? ‘‘Please dont write any­thing like this again. Or if you do then spare us of it.’’ He fol­lowed up with the (pre­sum­ably satir­i­cal) sug­ges­tion that the Mir­ror do a story on Starpath. Ac­cord­ing to the web­site gee­olo­gie it is – ‘‘a sprayable glow in the dark light­ing sys­tem that makes path­ways twin­kle like a bil­lion lit­tle stars af­ter the sun goes down. ‘‘The coat­ing is ap­plied in three lay­ers, with a mid­dle ag­gre­gate stage that ab­sorbs UV en­ergy dur­ing the day, which is then re­leased as a blue glow when it’s dark. ‘‘Man­u­fac­turer Pro-Teq Sur­fac­ing sees Starpath as a way for mu­nic­i­pal­i­ties to save money, by re­plac­ing costly elec­tric path­way light­ing with the low-main­te­nance coat­ing. In­stalling the sur­face takes only a few hours, leav­ing a durable coat­ing that’s slip and rain re­sis­tant.’’ Mr van Reenan adds: ‘‘Im sure that un­der the TPP [Trans Pa­cific Part­ner­ship] we could get a good deal on a bulk sup­ply of the stuff.’’
