this woman is listening to music through a bouquet of gerberas. they have been made into speakers by being inserted into an acrylic tube containing a magnetic coil and an oscillating component. Applying an alternating electrical current causes the tube, and the flowers, to vibrate at high speed, producing audible sound. skeptics say the sound may not be comparable to conventional speakers but perhaps someone could write a sound software tailored to the flowers to compensate for that.
