I take a multi-vitamin everyday, at least when I can remember to on days when I have to get up early and rush out the door.
On the days I forget, my urine comes out a fairly , well, I don’t know if you’d call it “standard” color but not an unusual color.
But on the days when I take the vitamins, it comes out neon yellow! I don’t mean pastel, I mean a very bright neon yellow!
Wow, this is cool. I wonder what other colors I can expect now!

If you drink the liquid in a chem-light your pee glows.
Don’t ask.

Okay, but do I have to snap my penis in half to get it to flouresce?

Taking a poo after drinking lots of grape Gatorade the day before is interesting to say the least. It comes out deep purpley blue. :eek: (No, there wasn’t any toilet bowl dye involved.)

Try pre-natal vitamins. I didn’t think that that particular shade occured in nature. The weird thing is how fast it happens: I take two large, hard, horsepills and within 20 minutes my pee makes Mountain Dew look anemic. 20 minutes! How the heck does anything digest that fast?
Except when I was really sick with a headcold and sinus infection. Interestingly enough, the pee didn’t get so neon, despite the extra vitamins I was taking (6 a day instead of 4). A little bright, but not as intense. So I guess my body must have been using more of whatever the neon component is. (My doc WAGged it was the B vitamins.)

When I was a hospital corpsman, I learned of a harmless pharmacutical that made you pee bright red. I swallowed the pill and maybe an hour later, I was peeing in a color that looked just like bright red blood.
Told the boys about it, they tried it, too, and then we fantasized about somehow surreptitiously slipping the pill to some of our Cuban buddies - maybe our girlfriends, even - in Gtmo City. We’d then spin a scary tale about a deadly disease that has popped up here in in the Oriente province, and how a team of navy MDs were quietly seeking the cure. Problem was, you feel fine, but suddenly you pass blood and two hours later, you’re dead.
No we didn’t follow through on this caper.

Yes and then shake it.

If I could shake it, I wouldn’t need the vitamins.

It’s the B vitamins, specifically [riboflavin](http://www.wholehealthmd.com/refshelf/substances_view/1,1525,962,00.html)

Or slip it to someone who’s about to go swimming in your friendly neighborhood backyard pool. :eek:

Was that methylene red that changed the color of your urine to red? I’d rather use methylene blue. Sure, it doesn’t look like blood, but… come on, blue pee.
So now we’ve figured out red, yellow and blue… we can make some serious snow art.

I have never peed in any colours other than plain yellow.
I feel so… so… so dull and untalented. ☹

Sometimes I pee Helium if I set my mind to it. But I’ve never gotten Neon.

Just try your friendly local B vitamins!
Haven’t seen anything but neon in a while now…

Sadly, I don’t remember. I was down in Gtmo in 1953-56. That’s a long time ago.

I believe theres a chemical you can add to a pool to make urine show up bright red in the water. Makes it easy to pinpoint “culprits”.

There’s also a mediaction commonly known as “green meanies” that make you pee flourescent green.
So with the right combination of drugs and plenty of beer, you could make a 4-color snow printer - the P-jet!
