Doing these types of things will in the end not prove much to my way of thinking.
A horse that is not reactive to something done in its barn, may well change and be a nutjob at another barn, due to feed, babying owners, or ignorant handling.
And if you did something like what you are suggesting doing, or have done to one of my horses? You'd be wearing that bottle, internally.
If you want to do something foolish with your horse, that you own? Fine, but doing it to someone else's horse is a major mistake.
Horses make me a better person.
