Portable Rock Climbing Walls
Rock Climbing is an urbanized form of mountain climbing. Even though the sport began as a recreational activity, it is considered today as the layman's favorite recreation and offers its very own thrills. The roots of this sport lie in Europe, and it has over 100,000 athletes involved in it. These days, Rock climbing is considered as popular as baseball and basketball in the United States.
Rock climbing is the only sport that demands strength and endurance. It also requires co-ordination of all five senses and mental composure to evade injuries and increase speed. For many, the sport may seem easy, but rock climbing needs continuous guidance to move from the basics to the expert level.
Rock-climbing is habit forming; it is so addictive that sometimes you wouldn't want a rock climbing session to end. In that case, enthusiasts seeking sessions on an hourly or monthly basis would run into financial trouble. This is where a comprehensive investment such as a portable rock-climbing wall would do well.
So, what is a portable rock-climbing wall?
A portable climbing wall is built with materials such as wood and iron. It offers its own set of belays and hooks arranged to represent actual climbing routes and their toughness. A portable climbing wall is of different types:
A Portable wall that has Stone-coated panels
This kind of portable will go easy on your pocket. The design is simple and includes well-defined angular faces. The panels have a sand coating and resin for added friction. This wall is considered the best for competition purposes as it can be constructed over large areas at minimum cost.
A freeform wall with a Stone-coat
This portable wall is for the more experienced climbers and includes coordinated angular faces. The frictional coating is a bit more superior and has a 'higher bolt on hold' per square meter ratio.
Portable wall with featured panels
Such a portable wall has the feel of a natural rock. Each panel of the wall is specifically designed with an even distribution of cracks, flakes and pockets. The interior system is 2-dimensional, taking up a smaller amount of floor space. The best aspect of such a wall is that the climber can himself decide on the placement of bolts and holds. This offers the user several different options of route on a single bolt line.
A Portable wall with a Digital Freeform
The most expensive among the four, this portable wall uses the design of a natural rock. This wall has many features and in certain areas includes hand sculpting in a three dimensional curvature. This wall is created on order and can be molded into any three dimensional shape. The shapes could include deep chimneys to big rounded aretes. The crack lines could be deeper with a bulging overlaps. The other smaller features included in this wall are pockets, slopers, jugs, and undercuts.
If you are looking for discount on a portable climbing wall, the best place to visit is a fair or festival where these walls are offered for testing purposes. If you are looking for a more-challenging make. you can browse the internet.

How a spectrum is displayed on the wall when using a pocket mirror and water?
Ok, so I am doing an experiment for class and found the results but don't know how to explain them. I placed a small tray of water in a windowsill containing bright sunlight. Using a pocket mirror, I leaned it towards the window and a spectrum (basically a rainbow) was shown on the wall. So how exactly does this work? The light does what? to make the rainbow colors on the wall.
I'm sure it has to do with refraction, but am at a loss for explaining it. Thanks for any help. 
Yes, it has to do with refraction.
Light changes speed as it moves from one medium to another (from the air into water). This speed change causes the light to be refracted and to enter the new medium at a different angle.
The refractive index of many materials (like water) varies with the wavelength (ie color) of the light used, a phenomenon known as dispersion. This causes light of different colors to be refracted differently and to leave the water at different angles, creating an effect similar to a rainbow. This can be used to separate a beam of white light into its constituent spectrum of colors.
