Oh I didn't spill mine. I stopped to step into the house and forgot to put everything away. The dry crystals had been in a stainless steel bowl on my work surface. It rained a bit. The wind blew a little. By the time I remembered I hadn't cleaned up after myself, the crystals were a beautiful green color. I mixed them into a batch of soil and used them anyway. What's a bit of algae between friends.
I didn't think to take a photo at the time but fortunately I found a good photo here:
