If you have been fortunate enough to witness a good display of bioluminescence in the ocean, [link] you will appreciate the ethereal beauty of the effect. Now you can bring the ephemeral loveliness home for you and your guests to enjoy on those warm summer nights.
Simply purchase our concentrated
5 litre bucket of specially selected mixture of dinoflagellates and algae then pour into your pool at dusk before your guests arrive.
The organisms will last for a few hours before the chlorine does them in and every swimmer will look positively elfin as they swim through the water. Another party planned next week? Buy another 5 litres of glowing happiness.

I've stood and swum in a bioluminescent sea
during a spectacular thunderstorm, and it is
indeed awesome. |
|
| |
Not sure that they'd survive more than a few
minutes in a pool - the osmotic shock would
probably kill them before the chlorine - but
perhaps I'm wrong, or maybe there are freshwater
bioluminescent beasts. |
|
| |
We could engineer a freshwater organism to be
bioluminescent, but making it respond to
shear/turbulence would be difficult. |
|
| |
You will almost certainly need a heated pool, what
with those organisms being tropical and all. |
|
| |
You might have better luck with the "sea walnut" a
comb jelly (non-stinging), which can survive at
least somewhat in fresh water, and as a larger
animal might survive the chlorine a little longer. |
|
| |
It wouldn't produce the same sort of halo, but
each swimmer would be followed by a trail of
sparkles. |
|
| |
And as far as temperature, bioluminescent tides
have been reported off Cape Cod (midsummer,
admittedly), and Sea Walnuts are year round in the
Chesapeake. |
|
| |
Are these organisms deadly-poisonous or is that just the red-tide Dinoflagellates? |
|
| |
Putting aside this mini-genocide of living things, how about some small white plastic spheres and some uv lights? |
|
| |
Or phosphorous? Just remember to rinse the guests off after they get out of the pool. |
|
| |
No no no. The point of the dinoflagellates is that
they only produce light when sheared (ie, in areas
where the water is being agitated). So the swimmer
is surrounded by, and leaves behind, a luminous
halo. |
|
| |
Look all you need is pattern recognition and tracking UV
lights... |

Ummm, aren't the Japanese protecting the plankton and the Sea Shepherd bunch protecting the whales? |
|
| |
I'm bunning with the stipulation that whatever you
use doesn't mess with your naughty bits. |
|
| |
When I was a kid there was this stuff called "Mr
Bubble" you'd pour in the bath that would make it
feel like you were peeing fire afterwords. I think
they've since changed it but I'm pretty sure they
used plutonium in the first formula. |
|
| |
A good budget version would be to fill a pool with
fluorescein and light it with blue lamps from the side,
would be pretty cool to swim in a big green-glowing
pool. |
