Ok, so I need to know one I can take in the car with me. And I already heard the get someone to pee on you one. Not interested in that for obvious reasons.
Not sure if it works. A freind told me someone spread shaving cream on the stung spot. They left it on for 3-5min and then scraped it off with the handle of a plastic fork. He said it took like 85% of the sting away.
You MUST find the SEA JELLY that stung you, so you can eat it. Then after you make your next bowel movement, you have to take a small sample from the toilet. Be very careful, this is the anti-venom. Put it a little bit in a syringe, inject it, and you should be good to go.
trident your correct...apply shaving cream leave for a couple of minutes scrape with credit card to get the tentacles off...the apply vinigar for 30 minutes...the stinging should go away within an hour
