Well, the surface of the spray coating is actually filled with nanoparticles that form a very rough and craggly surface.

So you've got traditional things like pepper spray, O.C. spray up at the top there, or Tasers over here.

Mark Shaw demos Ultra Ever Dry, a liquid repellent coating that acts as an astonishingly powerful shield against water and water based materials. At the nano level, the spray covers a surface with an umbrella of air so that water bounces right off. Watch for an exciting two minute kicker.

A windshield coating is going to give you about 110 degrees.

So one of the things I particularly looked at was the use of O.C. spray, oleoresin capsicum spray, pepper spray, by Australian police and seeing when that had been introduced, what had happened and those sorts of issues.

So if I put this inside this water here, you can see a silver reflective coating around it, and that silver reflective coating is the layer of air that's protecting the water from touching the paddle, and it's dry.

Now when they introduced O.C. spray in Queensland, they were really explicit.

Attempts to acquire specific spray dryers also failed for the same reason.

A standard catalyst free spray destroys fewer than half the spores in the same amount of time.

No evidence was obtained by the United Nations inspectors that Iraq had spray dried agent in bulk.

Children with this disorder have small teeth which, due to poor enamel coating, are prone to dental cavities and often require removal.

The interaction of this plasma with the electrodes generates ultraviolet photons, which then excite the phosphor coating on the front of the display.

They're not obeying the directions that we're giving them, so we'll give them a shot of the O.C. spray.

A solution for this researchers are hoping to find is a low friction coating or channel materials that help reduce the blocking of the tubes.

This energy is immediately converted into a spray of subatomic particles, with detectors and computers used to figure out their properties.

(Boats would spray seawater droplets into clouds above the oceans to make them reflect more sunlight back into space, reducing warming).

The environmental affects may include diurnal temperature cycling, vibration, shock, humidity, solar radiation, precipitation, sand dust, salt spray and electromagnetic radiation.

Forensic sampling and analysis of spray drying equipment present at Al Hakam in 1996 revealed no traces of biological warfare agents.

Dry water actually consists of 95 percent liquid water, but the silica coating prevents the water droplets from combining and turning back into a bulk liquid.

The material inside the microcapsule is referred to as the core, internal phase, or fill, whereas the wall is sometimes called a shell, coating, or membrane.

The person who's spraying the O.C. spray is wearing a rubber glove to make sure they don't get contaminated and so on.

Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas.

In the video, the umbrellas that protected the protesters from police pepper spray and tear gas were depicted as parachutes and ray guns.

These trials involved munitions supplied by the Iraqi chemical weapons programme and an aerosol spray device modified specifically for the biological weapons programme.

And now kinetic and architectural firms like Grimshaw are starting to look at this as a way of coating buildings so that they gather water from the fog.

What I have here is a cinder block that we've coated half with a nanotechnology spray that can be applied to almost any material.

Seawater has a higher refractive index than rain water, so the radius of a rainbow in sea spray is smaller than a true rainbow.

At that time, the inspectors had not fully understood or appreciated the specific features and markings black stripes and the different internal coating found in some of the bombs.

Experienced graffiti writers use different sizes of spray valves to control the spread and pressure of the paint, and refill the cans to save money.

The spray dryers at Al Hakam lacked the required biological safety containment features, which Iraqi scientists recognized as a necessary condition for their own protection.

The North Carolina State University's College of Veterinary Medicine in Raleigh, North Carolina uses both PC (plastic coating) and PN (plastination) to investigate and compare the difference in the two methods.

The report also called for water spray systems to fill up draining pools, but made this conditional on a cost benefit analysis conducted by each plant.

Two main opportunities exist through which current reliance on DDT may be reduced in a sustainable manner, where DDT is currently used for indoor residual spray

Anyone want to take a stab at the number of times, given how they've introduced this, the number of times police in Queensland used O.C. spray in that period?

I'm going to go out on a limb here and say that if Queensland police didn't have O.C. spray, they wouldn't have shot 2,226 people in those two years.
