The
Laser Fountain was a
relatively
unsuccessful attempt at Burning Man installation. It's a recirculating
fountain that sends water jets through three nozzles into a basin. The
trick is to arrange a laser to shoot out through each nozzle. Because
of total
internal reflection, the laser
light will follow the arc of the
water stream.

This was relatively simple to
arrange, using a pipe T-junction with a glass window epoxied across
from the nozzle on the crossbar, and the water input down leg. The
laser shines right through the window and out the nozzle, coaxial with
the jet. The long collimating nozzle helps generate a smooth unbroken jet of water. |

Result:
if you cup
your hands under the stream, you are rewarded with a
pretty handful of wet green light I underestimated its attraction for handwashing (as well as light-splashing), and I only brought two changes of water, which were quickly muddied. Like so many BM projects, dust was its ultimate downfall. |
