So, if it's the parbly dihydrogen monoxide frost (read, "deadly") that's the problem, why wouldn't the paper towel (or something stronger) solve that problem?

And, while we're at it, if you spray carbon dioxide out of a cylinder across a table top, does it really roll across the plane and then fall off the table like a waterfall? Is this true, as my daughter's boyfriend told her last night, or is this a case of a teenage boy trying to pull the wool (waterfall) over a gullible girl's eyes?

Best regards,
