I was at Puerto Plata/Taino Bay, Dominican Republic today on my cruise vacation (which is the reason why I haven't been uploading videos on Rumble) when I saw this barely visible rainbow over the geyser fountain. You can see it better in real life than you can on camera. I don't know what the geyser fountain thing is called and my basic wi-fi package doesn't seem to work with images on search engines, so I'm going to leave it to you guys to tell me in the comments section what that is.
