Last weekend we went for a walk in the snow and as we were far afield my friend Robert asked if itwas bad to eat snow
here is the warm fuzzy answer STOLEN FROM THE INTERNET (yahoo canada)
You should be fine as long as it is fresh and sitting somewhere clean. Don’t worry about the water being from dirty lakes or swimming pools…only the water evaporates up into the atmosphere, not the dirt.
Don’t EVER eat yellow snow!
