Don't know what you're talking about zaz...

the stings from nettles are a recognised cure(or at least ease from)arthritis.

the Romans, when they came to the damp, cold UK, used to rub nettles on their skin to warm themselves up

Chilli (capsaicin) is also used in topical painkillers: FiL swears by it for his knee

A few years ago I read a tip in a mag in the dentist to rub the cut side of half an onion on your windscreen to prevent it freezing. We had an old banger at the time and it used to take OH ages to defrost the windscreen so as a surprise for him I duly rubbed the onion on. I was so glad I hadn't told him, because it really didn't work - it took him twice as long to scrape it off and then get rid of the smearing, which to this day he has not been able to explain.

Wow! I didn't know this and I suffer really badly, I couldn't sleep last night because of it. Will definately try this tonight.

Hi Ollie - are you definitely going to try it? Let us know if it works for you too - definitely!

There's something wrong with my spellink today.

Spelling Police? I'd like to confess to a series of crimes

Did you know:
If the science existed to bore a hole through the earth from any point (A) to any other point (B), and it was possible to create a frictionless environment; then any object dropped into the hole at A would take almost exactly 42 minutes to travel to point B.
It doesn't matter if you drill the hole from London to Paris, or London to Beijing, it would still take 42 minutes. (42 minutes 12 seconds if the world was perfectly spherical).

Quite Interesting I think!

OK believe it or not half a cut potato rubbed over your windscreen repels rain! HONEST!

Works with apple too...

Um; wouldn't it stop halfway down? Or at least get to one point and then fall back towards the centre, and keep doing this until it stopped in the centre?

Depends if the moon's in Jupiter or not.

It'd burn anyways - that or be eaten by dinosaurs.

The momentum gathered during the first half of its fall would carry it passed the middle-point, where gravity would begin acting against it. Its speed would then decrease until it reached zero, at which point it would be exactly at the other end of the tunnel (assuming there was 0 friction in the tunnel).

It's a theory known as 'The Gravity Train' hypothesised in a letter from British scientist and inventor Robert Hooke to Isaac Newton some time in the second half of the 17th Century.

Must have something to with attraction between two poles. They could use that theory for underground travel once they sort out the friction bit.

I think you could cure most of the friction bit using magnetic levitation and a vacuum (probably). An even larger problem is that no substance is known that can withstand the temperatures at the earth's core. Forget your chilli, fingers, that's not even on the Scoville scale!

[bobleponge]

So is the earths core a complete vacuum then, devoid of all matter?

And who's been down to have a look?

Well it's all theory at the moment as they calculate it to be at a temperature of 5700K, a pressure of 330 GPa (that's 3,250,000 times the pressure air exerts on us). Oh and also, it's probably solid nickel-iron alloy.

Apparently...
