Inspired by a wrong answer given by rr (rhoitrau) to this question. You get the GQHero trophy: , nevertheless! :)
What are these genetically modified plants capable of detecting?
They turn red when they “detect” something.
Cracked by: shenoyvarun86 , krudebox , Dibyo , Gurupad , sidsen , shrik , udupendra , madhur , akhi , varuns88 , piezocake , KK , malcaluffin , Aditya , Raghuvansh , eli , Rogi , alephnull , Chinmaya U.Holla , Ps , prasanth , Mo , SV and Logik
These GM plants detect NO2 which generally seeps into the soil from land-mines, thus acting as a land-mine detector!
