From the "Bulbous Bow" entry in Wikipedia:

A bulbous bow, a feature of many modern ship hulls, is a protruding bulb at the bow (or front) below the waterline. Usually visible only when a ship is in drydock, the bulb modifies how water flows around the hull, reducing drag and increasing in speed, range, and fuel efficiency. Ships with bulbous bows generally have 12 to 15 percent better fuel efficiency than similar vessels without them. Bulbous bows achieve maximum effect at a narrow range of speeds over 6 knots (Bray, website). At other speeds, they can increase drag. They have the greatest effect on large ships such as freighters, navy vessels and various passenger ships. They are rarer on recreational boats designed for wide speed ranges and planing over the water.

Can you convert a inground pool with concrete bottom and polymer sides into a liner pooll?

I'm going to presume that it already had a liner in it once before.. there are only a few systems like you are describing. One is a stainless steel wall and concrete bottom (.claytonlambert), and the other is a (onlyevolution) composite (not polymer though) wall system that is painted with a painted concrete bottom. I think there is a company called Swimcrete as well.. but, either way, if you wanted to drop in a liner, you'd need to have some sort of coping or beadtrac around the top. If you could post a picture it would be helpful! The answer is "absolutely not"! The liner folks will be happy to sell you a liner, but it will not last 2 years. A hybrid pool lacks the required 'concrete receptor coping' installed in all vinyl liner pool installations. The required concrete receptor coping is extremely strong and contains what is known as a 'bead receptor'. All vinyl liners are manufactured with a 'bead' around the top of the liner. Obviously, at installation the bead is inserted into the bead receptor enabling the liner to support well over a hundred thousand (100,000) pounds of water. Even a small vinyl liner pool, 16x32, holds about 125,000 pounds of water. The vinyl liner salesmen, those without ethics, will nail a track into the top of the polymer wall, then screw the liner into the track. In other words, the 20mil liner with screw holes is expected to hold at least 125,000 pounds. As soon as the ground settles, even a little bit, the liner tears and you're out thousands of dollars. Better is resurface the walls with swimming pool gelcoat.

Why shouldn't you store toxic chemicals in metal drum?

Because the drum could rust through and release the chemicals, or be contacted by electricity and cause a fire...if you need to store toxic chemicals in a metal drum, you put a drum liner in first, and pour the chemicals into the liner. A drum liner is a very thick plastic bag.

What is the best kind of eyeliner that isn't waterproof for your waterline?

You could use MAC Fluidline, which is a gel liner. All liquid liners are not that waterproof, but I don't think that all of them can be applied to the waterline. You could also use MAC eye kohls, but those hold up a little better than liquid and gel liners. Hope this helps! -Beepbubby10

How do you do emo eyeliner?

That depends on which eyeliner you mean. Do you mean the pencil that goes across your waterline or the liquid eyeliner? Pencil- Pull down skin underneath the eyes and draw a liner of (thick) black eyeliner. If (like mine) your eyeliner doesn't work first time, run it across your right waterline and it should work when you go across to the left. If it works, go back across to the right and fill in.


What happens if you get liquid eyeliner in your eye?

It stings for a second. Then it goes away.Your eye will not be permanently damaged in any way, but the sensation is not pleasant. Avoid using liquid liner on the lower lashline or on the upper or lower waterline. It is for the upper lash line outside of your waterline only. If you apply it only there, you should have nothing to worry about.I hope this answer has helped you! =]

Should 12 year olds wear eyeliner?

Depends on where and the thickness. I have searched all over the web and have gotton alot of "yesses". Now, a brown pencil liner on the waterline is all needed. None on the lashline. If your daughter decides she wants to wear liner on the top, go and buy a chocolate eyeshadow (my favorite is Cinnamon Toast by Ulta, for it has a gold look to it) and have your daughter wet a lip tester brush, or a gel liner brush. Then dab the chocolate shadow on the wet brush, and have her apply like gel liner (only on the lashline THIN LINES!!) For 12+ looks check out makeupbyki on youtube(:
