Damballah Wedo Offering

I set up a appreciation offering today. I printed out a copy of his veve burned green and white candles. After I left the altar burring for 7 hours. I discarded the offering and cleansed my space and home. I set up my altar to get ready to burn Sire. Bubbles appeared when I first poured the glass of water. When I went to check the glass of water this is what I found. What do you all think? I poured the glass of water out and cleaned and dried it then filled it up again. I will let you all know what I find in the glass in morning.
