Happy St. Patrick's Day! Since today is about all things green, here are a list of "chemistry" projects that you can try to turn things green, among other suggestions. Green fire definitely sounds like an interesting one!

Phenolphthalein turns urine red, which might be even more disconcerting. And then who knows what happens when you eat some litmus paper?

<...Phenolphthalein turns urine red...> So does a diet consisting only of beetroot, which in addition has a similar coincident effect on all other body fluids... (Don't ask).

Things don't turn green here until May Day & the Jack-in-the-green festival.

I watched people drink green beer this afternoon.

Does that count?

It counts with me!

During my earlier educational years I always tried to be in the vicinity of Athens, Ohio, for St. Patrick's Day. Ohio University is located there and they have the green beer tradition. One bar, I don't know which there were so many we visited crawled to that year, apparently used a green dye that the body did not separate out of the urine. There were a lot of people either laughing or screaming as they rushed out of the rest rooms.

Methylene Red and Methylene Blue, both used in labs as indicators will do the same thing. Methylene Red is also used in those "exploding money bundles" that are given to robbers at banks. The stuff is also impossible to wash off. Takes up to several weeks to wear off. Just look for the person with the red face, hands, arms, etc.

Me, I will take red from kidney stones any day! At least I know who to go to for that!

Good Luck, Old Salt

I decided to avoid going out today. By about 7pm the city centre will be over run with pseudo Irish with terrible accents consuming vast amounts of Guinness and whisky. By 11pm things are usually getting out of hand.
