Friend of mine once did something like this to a tarantula we encountered while hiking. Spider had gotten about two-thirds of the way across the trail when we found him; Brian reached down and quickly spun him around 180 degrees. Spider kept walking, back in the direction he had originally come from.
When he got to the edge of the path, he stopped and looked around for a few seconds, no doubt thinking something like “how the heck did I get back here?” He then turned around and started crossing the path again. Again, when he reached the two-thirds point, Brian spun him around, and he headed back to his starting point.
They went through this about four times before we lost interest. But I learned that day that spiders apparently don’t get dizzy.
