If someone can take a look at my blend file and tell me what I did wrong. I'm trying to follow some YouTube videos, but I'm not sure how to get the water to work. I managed to get some water to work, but it flowed out of the bulb like it wasn't even there, and then there was a hidden rectangle around it that kept the water within that I never put there. And all of a sudden, the whole bulb itself turned solid black. I had to revert to a previous save because I have no idea what I had done. I'm just trying to make the water stay inside the bulb, so I can animate the cube drop in the water, then animate it floating in it.
I was able to get the water to come back, and this time I took a picture of how it reacted.
