So, I have been hand carving 30 message pods out of foam, sanding them down, priming them, and drilling tunnels in them for a couple of months now. I cannot express how happy I am to finally see them in action!
People litter a lot in the lake (notice the water bottle floating by the islands in the middle photo.) Whenever we pick up the floating message pods, we make sure to remove any trash in the lake that we find. Do not worry about the message pods getting lost and becoming litter themselves! They are incredibly stark white in contrast to the natural environment, so we easily spot them and pick them up.
We look forward to you all sending us messages in the near future!
