so i have to do a science project, and i thought, "hell, why not do skiing"

so basically i am testing out the effectiveness of different lubes on the speed of the ski.

ns, gimme some ideas for what type of lubricants i should test! i'll post which ones make your skis faster when i have done the experiment!

so far i have
1. butter
2. wd-40
3. synthetic motor oil

4. Brake fluid (Tip, try it last, it might eat away your base)
5. Ice Tea (Because it's so awesome!)

My friend swears by pam(or any other spray on anti stick kitchen product) but i think he's just and idiot.

and its an old ass ski so it doesn't matter if the shit hurts the base.

We use wax for a reason.


WD-40, oil, etc. will ruin your bases. Don't do it— they'll permanently make it harder for your bases to absorb wax, which you'll want to go back to after you finish your experiment.

Not to mention that (in the context of the experiment) each "lube" would permanently change the characteristics of your base material, giving you multiple experimental variables, and a teacher with half a brain would fail you.

yes, i know how wax works thank you very much.

and its been checked off by 2 teachers, apparently these teachers aren't experts at p-tex absorption. Its a high school science project for gods sake i don't really care how flawed the results are

hell even in college no one gave a fuck. just do a really good job of explaining why your results suck so much.

on that note, dont do the experiments, just make up the data.

i heard bobby wasnt getting enough speed for the x games big air jump so he plopped some spermicidal lube on his bases and he started overshooting.

When I used to race on Dryslope (don't judge), people used to use 'Mister Sheen' or other furniture polish, maybe give that a go.

dry (control)
wax (also like a control)

and whoever said it, ky. has to be done. or you could just test out different types of wax.

orrr... you could do something really cool, if you have the time and energy:


find the coefficient of friction for various surfaces (snow, ice, metal, turf, pvc, etc) my idea for this was to just drag a ski with a scale attached (like i did in high school physics) and use the reading to determine the friction. then you could use this to write a formula to almost exactly determine the speed you would have at any point. so basically you could draw up a setup (on hill feature, backyard turf and pvc, urban, etc) and even though there would always be some error, you could determine your speed in the tranny, off the lip, on the feature, on the landing, etc. and using the angle of the lip you could use the x and y speeds to determine your path of flight off a jump. i'm sure this has already been done by someone (for skiing, i mean) but it would be cool to have a key for each surface.


i think i'm rambling now, but regardless, it would be cool. and yes, i've thought about this before.

heres an idea. go to skibuilders.com, buy a sheet of p-tex and cut it into uniform sizes and epoxy them to uniform chunks of wood, then add your "lube" variables to the sample chunks and create a launching device onto some sort of measuring grid.

theres my two cents.

Animal Birthing Lube, AKA bovine butt goo.  Also synovial fluid - you just have to drain your own knee to get it.

Use an OLS regression, with dummy variables that are positive if each of the other lubes has been used previously, and nought if not.

Or, use two types of ski, and use a difference-in-differences approach for each lubricant.

This is a copy of reply to a post I made on the Mythbusters forum site.  I thought that would be a good place to get info on what I could use to make turf faster for summer set up.

The best lubricant you could possibly get is called synovial fluid. It has a coefficient of friction less than half that of Teflon, the world's slipperiest solid.!!!!
Of course, the biohazard risks and the fact that it isn't sold as a lubricant might hinder you, but just saying.

^ Synovial fluid is the bodily fluid that lubricates your joints.

car bumper polish and alloy wheel polish (like the spray on stuff for polishing crome) apparently works really well... It works well on snow flex! don't know about real snow though...

Not to sound like a douche but I'm pretty sure that Synovial fluid is not a solid..

what comes to mind is WD-4- and ANIMAL BIRTHING AGENT. seriously. also i saw on the history channel the government has this anti-friction super slippery stuff thats pretty legit. get ur hands on some of that!

No teacher with an entire brain should fail him.  It is good that he is going into this experiment with an open mind and doesn't just believe what people tell him. 

P-tex is used as base material because it naturally slides extremely well on snow.  Waxing was carried over to composite skis from preceding wooden skis and really serves no purpose today.  P-tex is hydrophobic.  Basically, if a water molecule cannot penetrate a ski base not much else can, especially a much larger paraffin molecule. Wax is only held on to a ski base due to roughness caused by today's finishing techniques.  Basically, we take a surface that was created to be as slippery as possible, and then take time and money to ruin it and bring it back to where it began.   

WD-40 nor "lube" would cause any permanent changes that a base grind could not fix.  The only reason I can think of as to why you would think WD-40 changes the characteristics of a base is due to the fact that it may not allow future wax to adhere to a base as well prior to a new base grind.    

OP, I would recommend purchasing some base material for $10 and just conducting experiments on the p-tex alone rather than an actual ski.  That way you can also test unaltered p-tex and will most likely see that it slides as good, if not better than a sanded and waxed base as well as any other lubricant you apply.

I didn't say the experiment's basis would get him failed; it's a valid experiment. It's that he seemed to expect to test each different experimental variable on the same pair of skis, and since each lube might affect the next treatment. I said a teacher with half a brain would fail him for a flawed experimental design, not for the experiment's basis.
