I was planning on using this to destroy pest, but luckily I have no pest and it turned out this gem works flawlessly under the lip wrapped in high tensile paper towel after being dried, cured and mixed with some water, K₂CO₃ and a pinch of table salt! xD
A cup of black coffee and a teaspoon of this mixture under the upper lip and I don't even want any breakfast. Amazing! 😍👌.
