I had to look up a word I was using (always do) and I found this definition:
immersible
/ĭ-mûr′sə-bəl/
adjective:
1. Capable of being completely immersed in water without suffering damage.
"an immersible hot plate."
2. Capable of being immersed.
3. Not capable of being immersed.
I love the idea that it means both potentials.
