I found a place that sells a gross at $20 ($0.07 each). Not much better. I
thought about bottles (free). But the deck would have to be removed to install
them. Next year I am thinking of replacing the deck so maybe. They are
certainly not flammable even with the caps epoxied on.

Put a pinch of baking soda and a drop of vinegar inside each
bottle, and tighten the cap. No need to glue the lids. The co2
generated by the chemicals will pressurise the bottle so it
doesn't lose bouyancy with cold temperatures and submersion.

The pop bottles will take a lot of pressure, they are designed to
avoid the danger of exploding glass pop bottles, remember those?
One little ding and kabloowie, hot pop all over, along with glass
shards.

Yes, the gas inside plastic pop bottles shrinks when cold,
reducing their floatation.

I have been hearing about people using ping pong balls for floatation.
However, I can't find anyone who has actually done it.

It makes sense in that it will allow water to flow and not trap water in
the bilge. They should last a while and certainly easy to install.

Anyone have any first hand knowledge of doing this?
