Constant Light without a source??? Is it possible to create a constant light using a laser pointer and two highly reflective parabolas. If the two parabolas open out to face eachother, and then you shine the laser into one, would the laser reflect until it reaches the centre and then continualy bouncing back and forth creating a constant light, at this point turning the laser off cause there to be no light source. Eventually this would fade out but is it possilbe. Any ideas on where to buy products for this would be usefull.
