But as you're in the UK I would be interested to see how the Royal Mail fares. Considering they have difficulty getting perfectly addressed letters delivered on time (or at all in many cases) my guess is "badly".

I recently bought a tub of "instant snow" polymer (a white powder) and joked to a friend that I would put some in an evelope and send it to him. It's pretty cool stuff actually - you put a teaspoon of powder in a glass, add some water and the glass overflows with "snow".
