what is the difference between water proof and water resistant?

water resistant means you can splash water on it and it will be fine. But do not submerse it in water. Waterproof means you can submerse it in water. All the seals are tight.

Because if absorbs more light wet than dry.

Look for inkjet sticker or laserjet sticker, they are different. Inkjet sticker of some brand can perform waterproof, but it can't resist to Ultra Violet since usually we used water based ink. So, better use Laser printer or dot matrix printer

no humans are not waterproof.\nwe are water resistant though.\nif you want an example next time your in a bathtub or pool look at your fingers they get pruney thats a result of osmosis or water transferin into/out of your body

Yes, they are designed to be permeable. So when dry they are very uncomfortable and tight. But that indicates a good fit (as long as you can still breath). They absorb water and trap a thin layer between your skin and the inside of the suit. Your body then heats up the water to work as a kind of jacuzzi to keep your body temp. up. If you get one that is comfortabme when dry, there will be too much room between you and suit when wet, and your body will not be able to properly heat the water. Good luck!

I think what that means, if I am not wrong, is water that is soluble and can mix with ink. Most pens have this feature, or should i say ink pens. They are not resistant to water so if there is water on paper, if you try writing over it, the ink would still make a mark on the paper instead of being repelled some where or not even made a mark. \n\nIf what I say above is correct then hop down to any stationary shop to grab some ink pens to see how it works.

if you have a map you  can put clear contact paper on both sides it's then water proof

None, unless you put some in it or it rains!

I know that my husband, who is a member of the water rescue team in our town, wears the long set of under-armour for extra insulation. They don't get wet under your wetsuit.\n\nMake sure you have a life jacket and a helmet.

Both are capable of performing well in salt water as long as there is a good flush after boating with fresh water. I live in Fort Walton Beach, Fl. , and you see alot of both.

Ceramic tile is pretty durable.  Cooler climates can make it more brittle, and it can break or chip if you have something heavy.  Porcelain is more prone to breakage until it is laid down, and then it is stronger than ceramic.  Other benfit is porcelain is the same color througout, while ceramic is terra-cotta color with a thin layer of enamel on top.

Tht won't be a bad idea, especially the waterproof ones.

From the Wikipedia:\n\nA wetsuit is a protective garment used for watersports such as scuba diving, surfing, windsurfing, and triathlon. A modern wetsuit is mostly made from thin neoprene, which provides limited thermal protection for activities in cold water. It is usually lined with a nylon fabric to strengthen it and make it easy to put on and take off. Some newer wetsuits, usually marketed as "superflex," contain spandex in addition to neoprene to allow the suit to stretch (the panels of a wetsuit of this type typically contain 15-20% spandex). This counteracts neoprene's tendency to shrink with age; it also allows for some changes in the wearer's size without making the suit uncomfortable.\n\nContrary to common belief, a wetsuit doesn't keep one warm by heating the water inside the wetsuit. Water has a very high thermal conductivity so heat is lost very quickly to the surrounding water. How a wetsuit works is all in its material, neoprene. Neoprene is a synthetic rubber that when processed to make wetsuits is mixed with small bubbles of nitrogen gas. These bubbles of nitrogen gas are what keep a person warm, due to the low thermal conductivity of nitrogen gas. The wetsuit must be a close fit to make the suit work efficiently; too loose a fit will allow the water to move around conduct heat away from the body. Flexible seals at the suit cuffs aid in the water retention. The suit loses buoyancy and thermal protection as the bubbles in the neoprene are compressed at depth.

Research shows that above spf 35 there isn't that much difference in the protection.  They key to using sunscreen is to use a higher spf, apply liberally, and repeat every couple hours.  Waterproof does not mean swim proof, it just means the water won't break down the formula, but it can still be mechanicially washed off with activity.  SPF applies only to UVB radiation, which primarily causes sunburn, but you will also want protection from UVA, which will be included in any sunscreen with a 15+ spf.\n\nDon't forget to stay in the shade when possible, wear sunglasses, a hat, and clothing when not swimming.  All of these can be effortless and promote healthy skin for life.

I used to be a competitive swimmer, and during some training sessions we had to wear multiple layers. They essentially create "drag" which increases resistance. Weight is offset by buoyancy, so to increase the resistance in water, you add clothes. Sweatpants/shirts absorb a lot of water, thus add a fair amount of resistance to a work out. While I'll admit, I haven't seen the aquacise classes apply this technique, it does come from sound water based training principles.
