Whenever I play my flute long enough it builds a ton of condensation that pours out the bottoms when placed up right. I get that moisture from your breath causes that but I found that it sometimes messes with the tone and playability. Is there anyway to fix this or is this just a quirk I have to learn to play along with? Or maybe my embochure isn’t rigt? Thanks for the help!
THis is natural and happens to all of us. I actually swab out my flute a couple times during an hour long practice session, as well as blowing out the moisture buildup. Doesn’t buildup as much at sessions if not playing on every tune, so not as much of an issue. I also switch between flute and whistle alot, and this helps lessen the moisture build up as well. You’ll get used to it over time. Weather and humidity and temperature may affect the condensation levels as well. 
yes, completely normal. Its worse when the flute is cold. I blow my flute out a few times during a long practice session. I notice the moisture can make the flute sound stuffy.
Just hold down all the holes and blow hard through the embouchure ( should sound like an elephant). you will see all the moisture come out. I do this before I swab the flute and pack it away as well.
For folks who use this method; Do you generally aim at the bodhran player or the box player?
Curious in Dartmouth.

You learn quickly that bodhran players have a stick in their hand … but box players don’t move very well with that thing strapped to their chest.
Carry a towel. Place the towel on the leg. Pat the end of the flute on the leg between tunes. It moves the condensation along and out of harm’s way.
Some flutes clog up (or bog down) worse than others. I have an M&E that I use as a beater/travel flute. Condensation has to be “blown out” frequently to keep it going when the climate is right (or would that be when it is wrong?). Other flutes don’t exhibit the same issue much at all.
Has anyone ever considered coating the bore of a flute with a hydrophobic material to keep the condensation from settling?

Avoid putting the wet dripping end over someones pint.
People give space to the pipes out of respect, but to the flute out of fear. 
Interesting idea. Too bad Rain-X is not supposed to be used for anything other than glass. I coat my bores with marine epoxy, but I suspect that qualifies as a contraindicated material. Though the epoxy itself tends to make droplets break off and run out.
I think Rain-X is silicone based. And silicone around instruments (or anything, really) is nasty, nasty stuff.
Right. Most of the hydrophobic coatings I know are silicone based. Variations on a theme.
MIT has developed Liquiglide. It is FDA approved for use as a coating in food packaging. It is said to be made from “all natural” ingredients. I have not read anything more than that yet. So I guess I’ll try reading the patent and see if I discover anything that sticks.
I think we talked about Liquiglide on the whistle board as a windway coating a while back.

Yes, last time I checked companies were allowed to use the term “all natural” to label virtually anything. In the world of food packaging anyway, “all natural” means absolutely nothing at all. The term “organic” is a different matter.
However, if the substance is sufficiently non-toxic to consider putting inside the bore, that might be interesting. Few of us use our flutes as drinking straws, so it might be all right 
That’s how I understand the “all natural” tag as well, Geoffrey. MIT does take their “green” description a bit further.
Not sure exactly what that means either.
Their description says that they create a permanent “liquid” layer on the surface of the product they coat. That does not sound great for timber flutes at first blush but polymer flutes should be fine.
Liquiglide is not available as a standalone coating presently. MIT works with interested parties to develop specific solutions for each with their proprietary technology. So it is not something any of us could just test in the back of our shops.
Or another, possibly more impactful, demonstration of LiquiGlide.

This is pretty cool. A material that’s hydrophobic in and of itself with no chemicals or coatings.
It is certainly not true that hydrophobic coatings need to be silicone-based. Organic chemists dial in the degree of hydrophobicity/philicity by putting different ligands in materials. And, of course, teflon has no silicon in it, although perfluorinated carbon compounds have been shown in the last few years not to be as benign as previously thought.
Very cool post, Kirk; I hadn’t heard about that. It’s not unlike something, IIRC, from the 70’s – the blackest black had been made by etching a silver surface with a particular acid mixture. That led to a surface rough on the appropriate scale to be something like 99.99% absorbing.
