It's been so long that i'm suprised it's still for sale. I bought some in'64.
Morning Breeze Stink Perfume it can be had at tricks4sale.com. It is a very low concentration of H2SO4,
suspended in an oil base. One application lasts a very long time. The smell....The most rotten, sulfurus eggs
come to mind. Like the one that wasn't found for two years after the Easter egg hunt.
A couple of drops in his waste basket will do the trick. The gas it lets off is heavyer than air so he will have plenty of
time to enjoy it, he might even like it. Who knows?
H2SO4 in high consentration is oderlrss and can take a life quickly. Just a word of caution to the junior chemist
that may have access to this deadly stuff. I use to work around oil rigs and when the well was in a pit, detectors
were sent down to be sure it was safe. Not a lecture just a precaution. 🙂
