how do water slides work?

The water on the slide is in a thin film and you aqua-plain along on the the water, much like a car skidding on a wet road.

Specifically, I do not know.  However the principal of a slide rule is that it utilizes natural logs of numbers.  Specifically, the natural log of the product of two numbers is the inverse log of the sum of the two logs... or, in normal terms...\n\nln(a*b) = exp( ln(a) + ln(b) );\n\nSo the way to do this on a slide rule is to add the two natural logs together and then calculate the inverse..

I not sure about this. Water has a lot of Weight. Ever see those "Slinky" toys. You not want you Pool to get the same idea as a "Slinky". Maybe you could Build Up the ground to get it level? Maybe a few Landscaping Timbers or even rocks laid nice and fill in to get it more level. I have wanted to do the same as you, but, with the slope I not think it will work, hate to spend money to watch it Collapse and be Ruined.\nQ: Where (and on what surfaces) can I safely and successfully set up my Simple-Set pool?\nA: For proper pool functionality and your safety the pool MUST be set up on an extremely flat, level, and stable surface. Suitable surfaces include grass, compacted earth, concrete, or pavement. Use of a ground cloth, if provided, is always recommended and is REQUIRED if the pool is to be set up on concrete or pavement. Under NO CIRCUMSTANCES should the pool be set-up on wooden decks or other wooden surfaces, or on ground that is muddy or subject to shifting. DO NOT USE SAND to level the ground, as it is also subject to shifting under the weight of the pool. Do not attempt to 'jack up' the pool on any type of frame, support, or riser(s), as this will cause the pool to collapse!

Okay I think the other 2 answers you already had when I started this misunderstood your question so I'll get it right for you.\n\nTwo things happen in the 16 seconds.\n1. rock falls s meters\n2. sound travels back up s meters from water surface to well opening\n\nFirst let's deal with the #1 part, the rock's fall.  For this let's use a variable called t1 for time.\n\nWe need to use this formula: s = (v1)(t) + ½(a)(t)²\ns = displacement, v1 = initial velocity, t=time, a=acceleration\n\nSince the rock is dropped it has no initial velocity.  Let down be positive.\n\ns = (v1)(t1) + ½(a)(t1)²\ns = (0)(t1) + ½(a)(t1)²\ns = ½(a)(t1)²\n\nOkay so we figured out what we can in this step about t1.  Now let's go to step 2 and see what we can figure out about t2.\n\nThe sound travelled from the water up to the well opening (s meters) in some amount of time we don't know yet (t2).  We can describe the sound's movement with this formula:\n\ns = (v)(t) (we use this because the sound is not accelerating)\n\ns = displacement, v = velocity, t = time\n\nNow let's use our variables (t2, our s) and use v2 for the sound's velocity and see what we can put together with the sound.\n\ns = (v2)(t2)\n\nOkay so we know something about the sound and rock now, let's gather what we found and look at it.\n\n1. s = ½(a)(t1)²\n2. s = (v2)(t2)\n\nThere is something else we know too and can write down as an equation.  We know that the time it took for the rock to hit the water and the time it took for the sound of the splash to travel back up to the opening add up to a total of 16 seconds.  So we can write it as:\n\nt1 + t2 = 16s (let's isolate the t2 and call it equation 3)\n3. t2 = 16 - t1\n\nSo all together we have:\n\n1. s = ½(a)(t1)²\n2. s = (v2)(t2)\n3. t2 = 16 - t1\n\nWe have enough equations now to solve for the number of variables we have.  Start by substituting t2 from #3 into #2 to get equation #4.\n\n4. s = (v2)(16 - t1)\n\nNow set 1. and 4. equal to each other (because they are both s so they are equal so we can do that)\n\n(v2)(16 - t1) = ½(a)(t1)²       (expand it out now)\n\n16(v2)-(t1)(v2) = ½(a)(t1²)\n\nNow put in what we know (v2 = 345m/s, a = 9.8m/s)\n\n16(345)-(t1)(345) = 4.9(t1²)   (move it all to one side and it should look familiar)\n\n4.9t1²+345t1-5520=0  (it's a quadratic equation and we can solve those, stick it in your calculator)\n\nt1 solves to\nt1 = 13.436\nor\nt1 = -83.844 (forget this one, the rock didn't hit before you dropped it)\n\nSo t1 = 13.436m (we only know this to 2 significant digits)\n\nNow we can finally solve for s by using equation #1\n1. s = ½(a)(t1)²\ns = ½(9.8)(13.436)²\ns = 884.57m (only to two sig. digits)\n\ns = 880 meters

I think it's real water when they made it look like it was raining, just like they do for Universal studios. Have you ever been there before? If not, they have a piece of equipment to rain when they want it to. The water prior to that I think was done by CG. It would have to be as well as physial special effects. Hope this helps.=>

Waves are formed by putting directional kinetic energy into water and the surface tension of a liquid acts like a jump rope when you whip it really fast.

We have used the Chromium technique when making slides but for our purposes we found this doesn't work as the Chromium diffuses into gold over several days. You can use a technique such as allowing the clean glass slide to soak in PDMS and a solvent for several hours, rinsing, dry (preferably clean air line), and then place into a vacuum/heat chamber and allow the gold to coat the surface of the slide.  Done!  Check out some scholarly articles...more detailed explanations are available in experimental sections of research journals.

(The total energy) = (kinetic energy) +(potential energy)\n\nAt the start, most of the energy is potential energy. \n\nAs you slide down, then the potential energy decreases and the kinetic energy increases. \n\nThere is some energy dissipated by friction, that turns into heat. But without friction, the total energy at the bottom of the slide is the same as it was at the top of the slide.

You have some very good answers here but I can add a little more.  Consider a pipe to be elastic (true!) but imagine that it is made of rubber.  Consider water to be nearly incompressible (a cubic inch of water at the bottom of the 7 mile deep Mariana trench still measures nearly a cubic inch).  Water can possess energy in two ways (neglecting heat); pressure energy or velocity energy and can easily convert back and forth.  When you extinguish velocity of a slug (or stream) of water you produce pressure and the pressure when relaxed can produce velocity.  This can go on and on until the energy is dissipated for example by friction.\n\nWhen a stream of water is flowing along an elastic pipe (think rubber) and you suddenly trip shut a guillotine valve (very fast acting) the velocity of the column of water is instantly extinguished and converted to pressure which starts as a shock wave stretching the rubber pipe toward the upstream end perhaps until it reaches the vessel supplying the water.  But the stream is then reversed as the rubber pipe relaxes squeezing out the water toward the vessel and continues until the rubber pipe is under a partial vacuum and shrinks.  In an ideal system (no friction), pressure waves would continue the travel back and forth along the pipe converting pressure to velocity and back to presure as the pipe expands and contracts under the changing pressure.  They call it water hammer because it actually can sound like someone hitting the pipe with a hammer.  Actually the pipe expands suddenly sending off a sound wave through the air.\n\nWater hammer can be avoided several ways.  For example if the pipe also contains air bubbles (accidently or on purpose) the bubbles will absorb any hydraulic shock wave preventing the elastic pipe from expanding and the bubbles re-expand slowly, slowing down the entire procedure.  The plumbing leading to many sinks in homes has a small "empty" vertical section near the sink to hold an air bubble which avoids a water hammer if the sink faucet is shut too fast.  It is sometimes necessary to drain the system with valves open to refill the air trap with air if it gets waterlogged.\n\nWater hammer can be avoided by shutting valves slowly rather than instantly.  Water hammer can occur in a pipe filled with steam because steam is easily compressed compared to an air bubble and a slug of water can be accelerated along a pipe by condensing steam until it "strikes" the end of the run and converts velocity to over-pressure.  I once got a frantic call at home (3 AM?) from a power plant under construction.  While testing a large pipe run for the first time under steam, the long say 12-inch pipe began to jump around threatening to break its pipe hangers and making a terrific racket.  Almost without waking up I told them to crack open any lowpoint valves or fittings to drain off all condensation and the pipe went back to sleep too.  In the finished plant there were automatic condensation drain valves to avoid water hammer which could damage the steam turbines too, etc.

Well for sund waves you can use the tuning fork and cup of water demonstration. As the water absorbs the sound waves it will ripple with the same vigor as the tuning fork. As far as light waves you can use the same glass and direct a flashlight through it to show how the water bends the light. Hope this helps.
