I did something like this.
I found a spider, decent size.
Placed him inside a plastic container and filled the sink with hot water.
I placed the contained inside the hot water and put a weight on it so it doesn't surface.
Seconds later the spider quickens his movement.
Then he gets into a fighting stance; starts attacking the air.
He stops moving, I get in to check and he's alive once the colder air rushes in.
I later pulled him out and flushed him down the toilet.
"Back to the sea where he came from :3
