If I placed an ordinary slice of bread in the bottom of a vaccum sealed 12" glass cube .. and placed it in direct sunlight , would my slice of bread curl up and dry ?
I would say yes it would, the bread would still contain moisture and as a result of exposure to sunlight, the moisture would be released, resulting in the bread curling up due to shrinkage. The moisture would condense on the sides of the glass cube.
This reminds me of that age old question...........
What would happen if an unstoppable force met an immoveable object ?

One for the chemists and mathemagicians. If you always fill your petrol tank when there's 10% left, how long before there's none of the original fuel left in the tank?
@Eiron..... I put 17 quids worth of petrol in my Diesel Mondeo Estate. realised my error and put 45 quids worth of diesel on top.......ran like a dream. No idea when i had ONLY diesel left though.
Probably wouldnt have worked if my Car had been a petrol one.
AJ, in the days when trucks didn't have fuel heaters, we used to put a couple of pints of petrol in the diesel to prevent it from freezing in extreme cold weather conditions, had no adverse effects as petrol is a more refined product. However, deisel being less refined and needing to be put under pressure before ignition can occur would most certainly have ruined your day with the outcome in a petrol car.
