The mine-flowers

This is not really related to my blog or my trip but as nothing happened today, this is more interesting.  On the same note as the “mine-sweeper rats”, we came across some “mine sweeping flowers”.  Someone somewhere (not Africa) has created a genetically manipulated flower that is white, but changes colour to red if it reacts with chemicals found in land mines.  To find the land mines you have to first saw the flower seeds over a whole minefield and then wait until they bloom to see if there are any mines around.
