how do you vacuum seal water, and how?

Freeze it first, then vac seal with "Food Saver" machine

Make a box of strong glass or reinforced cardboard. Put the mobile inside it and use a vacuum cleaner to suck the air out of the box. Make it airtight. Thats it.

You are using the term "mask clearing". That means exactly that, clearing the mask of water. I see everyone else is assuming you mean "mask defogging", which is not what you have asked.\nThere are two methods of mask clearing.\nIf your mask has a built in purge valve, it's a simple matter of holding your mask against your face and exhaling out of your nose. The purge valve is located directly under your nose and will open to let the water out. It shuts when you stop exhaling through your nose.\n The second and more common way, is to get your body vertical in the water column, tilt your head back a bit and with a free hand lift the bottom edge of your mask away from your face and exhale through your nose at the same time. Continue exhaling until the water is gone and you have seated the mask back on your face.This forces most of the water out of your mask.\n If you find that you're constantly having to do a mask clearing, there are three possible culprits.\n1/ That mask simply doesn't fit. Your face is unique, masks are mass produced to fit many but not all people. Test fit them in the store before purchase, without using the mask strap. Place it against your face and inhale a bit from your nose with your mouth shut. If it doesn't stay on for 30 seconds at least, it isn't a good fit. Move on to the next mask.\n2/ Your mask strap is on too tight. Too tight mucks up the seal on the mask skirt. Try loosening the strap.\n3/ You have hair trapped under the mask skirt or the skirt isn't seated correctly. If you're diving cold and have a hood on, you also may have part or all of the hood under the mask skirt. I've seen warm water divers put the entire mask skirt on over a hood, believing that was correct. They found the hard way, it wasn't.\n For your pool and eventual OW dives, eventually the instructor will have you do a complete mask removal and replacement with clearing. It's no issue, just remember to inhale through the reg and exhale through your nose as you put that mask on. When you're done, he'll likely give you a handshake for a job well done.

Ziploc works real well...biggest thing is to get as much air out of the bag to keep it the best.  Anything that will seal air-tight will work.

You know how when you suck on a straw you get your drink to move up through the straw? This happens because by sucking, you are creating a partial vacuum on one side of the straw, and the atmospheric pressure on the liquid on the other side, now having nothing to counter it, pushes the liquid up through the straw. But no matter how much you suck, you cannot reduce the pressure on your side of the straw to less than zero (i.e. a complete vacuum), and as such there is a maximum height to which you can raise a column of water - that height depends solely on the atmospheric pressure on the other side of the straw. This means that you can construct a barometer simply by having a glass tube immersed vertically in some liquid, and pumping out all the air on one side of the tube, and then sealing the tube - the height of the liquid then gives you the ambient air pressure. Water, however, is not very dense, and so your barometer would have to be very large if it used water. To get around this problem, scientists use Mercury, which is a much denser liquid, to measure the pressure. A pressure of 1 mm Hg is simply a pressure that can support a column of Mercury 1 mm high under this arrangement.

use a can of compressed air

To start with, the air and water would leak out of the station. The vacuum would not leak in.\n\nOnce the water droplets had passed through the hole, they would boil almost instantly into a gaseous form.  This conversion from liquid to water vapor would absorb a lot of heat (latent heat of vaporization) thus causing the temperature around the reaction to drop. This would have the potential to freeze some of the water before it has a chance to vaporize.

first off if you have an above ground pool to operate the (litleman) aka bottom of the pool vacume you have to fill the vac hose with water the you take out the fiters basket and their is a hole when the filter is on you will feel some suction that is whear you hook up the vacume hose after it has been totaly imerged in water and it is filled with water but turn the filter off before sticking the vacume hose in the hole in the bottom of the skimmer where you just took the basket out the turn the pump on the vacume may get stuck and you may need to help in out a little. To add filter sand i can not give you adaquate instructions because all filters vary so some take more sand some take less sand. But i hope i helped you out.    \n\np.s if you need more help email me at efmc1101@yahoo.com or contact your local pool store

Definitely a clean water and damp cloth.  Don't use any cleaning agents.  The little book that you got inside the bag when you purchased it should have instructions, otherwise I tend to always ask the Louis Vuitton store attendant re care instructions when I purchased the bags.

Shut off all taps and faucets. Repair all leaks. Don't allow it to drain away. Use water harvesting methods to collect rain water, which can be used to wash a car, flooring and for watering plants\n\nUse only as much as is required.

Turn off the vacuum.\n\nremove tube from vacuum to flask.\n\nLift edge of filter paper.\n\nJust do something to break the vacuum.

True, you can use spit but it really doesn't seem to be as effective as defog that is sold in dive shops and some sporting goods stores. Baby shampoo works well too. My favorite is liquid dish soap! I know, it doesn't sound like a good idea but hear me out.\n\nWet your goggles and place one drop for goggles. Masks may need more. Spread the liquid evenly. RINSE WELL (I give my mask a few shakes in the water) to avoid stinging later on. Do not use your fingers to rinse because you will remove the film. Your fingers have oils that will cause your goggles to fog too.\n\nThe reason I like dish soap because it is cheap and readily available. Most are biodegradable.\n\nWhy it works...after washing, dish soap leaves a 'sheeting film' that prevents dishes from leaving water spots on dishes. It is gone after it evaporates. When you wear a mask or in this case goggles it traps moisture inside so it doesn't evaporate.\n\nYou may have to reapply if you remove your goggles for too long or often. Remember to rinse it well. I have used this for hundreds of diving customers with no allergic reaction but if you do get irritation, discontinue.

there are some chmicals you can buy for cheap but the free way is to spit into them and rub it , then rinse with water and ware.\nDon't be disgusted, the navy seals and scubadivers do it

Best method if practical is to freeze it.\nIf not sealed within a steralized container.

Fill the tin with a small amount of water (approx 1 cup)\nHeat over a bunsen burner until water is boiling well.\nuse two fingers (inside a GLOVE) to screw the lid on the tin.\n\nPlace the tin in cold water, picking it up with 2 fingers..\nThe Steam from the water boiling displaces the air inside the tin, when you cap the tin and place it in cool water, the steam condenses back to water, a reduction in volume of 1725 times. This creates a vacuum inside the tin, and air pressure, 14.7 pounds per square inch, CRUSHES the tin

ONLY used compressed air.  NEVER use a vacuum on the internal portions of a computer!  The static electricity doesn't go well with the silicon parts.

wipe it with a clean cloth, or use compress air
