Let me start with a warning that this post brings up my true geekiness! I usually have a cup of coffee each morning that I take with me in a travel mug to work. The travel mug keeps the coffee hot for a longer period of time. At the start of this year I finally went in for the annual blood draw my doctor asks for...about 8 months late! My annual physical is coming up so I figured I'd better get in and do the blood draw my doctor ordered at my physical LAST year! I always go in when the office opens because a blood draw requires me to fast with no food or drink, other than water, after bed. That includes coffee. Okay, not that big of a deal, but it was really cold out and I didn't want my coffee in my travel mug in the cold car getting cold, so I did this to it.

| Travel mug wrapped in foil. |
I wrapped my travel mug filled with coffee with foil. Foil acts as a good insulator to retain heat, thus keeping my coffee warm. My wife may have given me a weird look in the morning and those at my office watching me carry this foil wrapped mug were probably wondering what the hell I was doing, but you know what? My coffee was still hot! And that's all that matters! :-) The moral to this story? If you're trying to keep something hot (or cold), foil is a could substitute to use when in a pinch. It retains heat in and prevents additional heat from entering.
