No this is so dumb. Candle wax does NOT > no wax at all. Candle wax, if anything, makes your skis slower. Much slower, candle wax grabs at the snow.
I can imagine the relation you made between candle wax and ski wax: "Uhmmm, their both waxes right?". They are almost completely different from each other other than the fact that they are both solids at room temperature and melt with a little (there are a few other similarities too). But really, there is a lot of tech that goes into ski wax.
If you think I'm wrong. Take flat piece of plastic, get a small block of wood or a snowball with a flat side.
1.Place that object on the plastic at one end and slowly raise that end until it slides. 2. Wax half of each side of that plastic with one half candle wax, and the other half ski wax. Repeat step one two more times placing your object on the ski wax half first and candle wax next.
The higher you have to bring it up, the higher the coefficient of friction between the two surfaces.
Your results should be as follows from lowest to highest (that it was raised): ski wax (using snow), ski wax (using wood), no wax (using snow and wood/same result), candle wax (using wood), candle wax (using snow)
Try it I dare you.
