Sitting out the back cleaning shoes and finishing them off water repellant spray it got me thinking...

If you were to spray your entire body from tip to toe in a superhydrophobic substance and jumped into the deep end of a pool would you sink and or drown?

YouTube "Ross Nanotechnology's NeverWet" for an example of what I am rabbiting on about.

For what it's worth I think you would be a goner, but I would be interested to hear what others think.

You would float. It would make no difference to your density, (assuming you floated previously)

I'm pretty sure that the human body is more dense than water, hence you would sink unless you were actively treading water.

Well, I float. Always have done. Granted, I have air in my lungs, which may help. Either way, if you sink before, then you would sink after, and vice versa.

No different from normal - though it is tempting to suggest you would go 'boing!' back onto the side!

I would think that you wouldn't be able to tread water water with the hydrophobic cover applied.

Why not? You would still apply force to the water with hands, feet, etc. the water would still move when you used your hands as paddles, etc.

The real question is, once you were in the water, if you 'pushed off' from one side, would you go faster?

  • runs off to see how much a tub of Ross Nanotechnology's NeverWet is.

It isn't commercially available yet. I've been keeping an eye on it for a while. I want to make stuff waterproof too.

Well, you'd have less drag, so faster, I would imagine yes.

You may also be dafter if you smeared that stuff all over you. Would you never need a shower again?

Only one way to find out I suppose...

No you wouldn't.

In answer to the OP, you're already covered in a waterproof coating. Do you sink?

Meh, my momentary evaluation of the hypothetical situation resulted in me going "Yeah, it's plausible" hehe

A scientist I am not. I pour a mean pint though.

Could get the OP to waterproof himself and then have a fight with a shower?

Only if there is a soap on a rope.
