Would not recommend using this on real batteries, but if you end up finding fake ones - spraying compressed air upside down (so it comes out as a liquid) and coating an object in it will make it very bitter, as compressed air commonly has bitterant in it to prevent huffing it. I used it myself to prevent myself from biting my nails.
