Nicanor, I saw your other thread about the water hyacinth. Rather than create a new topic each time, you can edit the existing one. The edit button is on the top right. Or you can go to the bottom of the first thread and at the bottom there's a tab that says --- Post Reply --- This adds the new stuff to what was already posted. Three photos can be added to each post.
So it takes a day for light to pass through this glass? So this was yesterday's tiny ad?
