to answer the questions...

I was drinking out of a stainless steel thermos and I had been given instructions on how to drink out of it (by someone who will remain nameless) and that was incorrect. It came out of the sides of the spout instead of the hole that I thought it would, and it dribbled down my chin instantly blistering it. It hurt/s pretty bad, but I hear that mouths heal quickly. That is the long and short of it. Word to the wise. Use the lid that doubles as a cup when it comes to thermoses. P.S. The beverage was still warm the next day (17 hours later) that's a quality thermos!
