I have this information so far:
1. Distance from the earth to the sun= 92,900,000 miles
2. Height of a Pop Can= 4.875 inches
which when converted to miles= 7.694 X 10^-5 miles
3. Height of a Mole of Pop Cans= 4.633 X 10^19 miles

Now, what do I do to find how many times it would go to the Sun and back?

Here's what I did, is it right?

92,900,000 miles / 4.633 X 10^19 miles
=2.00518023 X 10^26 times

Have storm clouds fallen out of favour? Now rising air cools and produces towering cumulus and cumulonimbus clouds. Are clouds not now given credit for the production of hurricanes? At one time it was thought hurricanes couldn't start without strong clusters of thunderstorms drifting over warm ocean waters! Now it seems that the hurricane produces the clouds and not vice versa. Right or wrong all that is needed are the details.

So I think I have discovered a new equation:
Beer + Cigarette butt = homemade volcano
Why???

After drinking 2/3 of a miller highlife last night I threw my lit cigarette butt into the bottle. About thirty seconds later the bottle was overflowing. I was pretty intrigued so I tried it again and the same thing happened.

I've been thinking about it all day and can't come up with a good scientific explanation.... Can you?
