When engineer Gregory Mathy created the first bimetal flower, his goal was to present his mother with a unique gift. These flowers respond to the heat from the sun to bloom during the day and slowly close again at night. While they do best when placed outside in the sun, Mathy says they can be displayed in pots or vases on a sunny windowsill, too.
Mathy's flowers, called Bimetal Creations, are part of a KickStarter initiative to fund their production. In return for a donation of $39, Mathy will hand produce a flower in the color of your choice at the end of the initiative.
These amazing flowers contain no solar panels, batteries or motors. They work by the expansion and contraction of the two bimetalic strips that respond to temperature changes.While attractive, they do have a bit of an otherworldly effect. Check out the video to see these flowers in action.
