Why,scientifically speaking, does urine make bubbles?

urine contains urea, which is a nitrous acid that is digested out of the bloodstream. when the urea mixes with the toilet water, it foams.

The caffeine in coffee acts as a diuretic and increases the rate of excretion of Sodium (Na+).  In short, it causes your kidneys to pump out more "stuff" into your bladder, thus increasing the amount of odor causing substances in your urine.

It's not healthy if you have bubbles in the jacuzzi. The soap and such can get in your urethra and cause you to get a bladdar infection which may spread to your kidneys. It's also why they say for females not to take a bubble bath.\n\nSo it's perfectly okay if you do it as long as you leave out the bubbles.

Yes, it's an old trick that divers used to do.  The ammonia and acids in the urine soothe the sting of the jellyfish venom.  Not to mention that your urine is THE MOST sterile thing to your body.  It helps stop the inflammation, which is most of the pain.

Because the diabolical megabucks conglomerate Coca Cola corporation knows if you pee more, then you'll drink more.\n\nSo they have many evil genius mad scientists who slave day and night, make arcane encantations to unholy dark lords, and barter with extraterrestrials and beings from warped dimensions to produce additives which they add to cauldrons of bubbling Coke while dancing naked and teasing poor teenagers with acne for the sole purposes of making you pee more so you'll drink more Coca-Cola.\n\nNow, if you want to know why you're always thirsty right after you finish a Coke, well.................

your blood sugar is really high, and when it gets high to a certain point the sugar gets into your urine, and the sugar absorbs water out of your body so it makes you pee more so you have to drink more to make up for the water you lose

Have you been taking vitamins or supplements? Usually when you take in more than you need, your body will excrete it in your urine and it may look flourescent.

cloudy urine is either a sign of a urinary tract infection which can be diagnosed and treated by most any health clinics (milder cases by drinking plenty of cranberry juice), or it could be a build up of uric acid from overexercising, rapid weight lose, low fluid intake, or obesity.  If its the second reason, you are more likely to get a kidney stone or maybe even gout.

Liquids like water usually have high surface tension meaning that they tend to minimize their surface area. Now this also means that stretching such a substance  (like you do with a bubble gum) is difficult. \nWhen a substance known as surfactant (used to decrease the surface tension of water) is added, the surface tension decrease and stretching the surface is more easy. It becomes now easy for the liquid to trap a certain volume of air and stretch its flat surface to form a bubble.\n(It does not mean that plain water does'nt form bubbles at all - it does so (as you observe when you pour water from a faucet in a glass) but the bubbles quickle is finished as the high surface tension forces the surface to minimum area - the flat surface.\n\nSo it is clear that whenever you decrease the surface tension of a liquid - by adding a surfactant (detergent in common household) it enhances the bubble formation by little agitation of the liquid.

The odds are pretty slim!  Unless you have a catheter that's obstructed in some way and the urine cannot flow out, the odds of your bladder bursting because you "hold it in" is extremely rare.  However, by holding it in, you increase your chance of getting a UTI (urinary tract infection), because urine is an excellent place to harbour bacteria.  Also, holding it in is harder on your kidneys than anything else and it will make your urine much more concentrated.  Not a good thing.

Some people get extremely nervous when they have to produce urine to others,  as result have difficulty in urinating.   This is what they call a shy bladder, but by no means is it a fact.   So you may be given an opportunity to try for awhile longer, or you may have to go to jail.   Only your probation officer can help you with this one.   But I have did urine screens for over 20 years and every one can give it up when necessary.  Judging from your situation,  I would say that it is necessary.   When my people have had a problem I let them hit the water , because no bladder is so shy that it won't release the water when it has had enough. Right now all I see is that you get nervous and have not been able to give a sample.   Hit the water, as you don't want to continue wondering if you may go to jail every time you meet with your Probation Officer.

Perhaps it makes you think of water, and water makes you think of urination. It's a connection... Think of water, think of urine. Think of hot, think of fire, you get what I'm saying?

Floaters are turds that have an unusually high gas content. Sometimes the gases produced by bacteria in our gut don't have a chance to collect into a large fart bubble, but remain dispersed in the feces. The poop then comes out foamy, and has a lower density than water. Poop with a high fat content will also float.

Hey, are you talking about two "eyes" in the sides of the end of the foley tube that sits inside the bladder? If so, they're there to let the urine drain out more efficiently. If there was just the one big hole in the end of the tube that sits in the bladder, then "low-lying" urine would be too low to make it out of that hole.  That's why there are those two "eye" holes in the sides of the end of the tube.

Everything farts to get rid of bodily issues  (or gasses)  So Yes they DO fart and the probably make bubbles because it is a gas being released into water.

I suspect that the calcium in hard water becomes kidney stones. Buy a calciun suppliment if you need more.
