okay this is my side-by-side comparison of the Stanley thermos on the right I've
had that for years it's ancient well let's see you 95
well not quite 20 years huh anyway what I did was fill both of these up and then
pour the water in here so I got just enough to boil a refilled each one of
these with tap water as hot as it could get
I'm gonna let these heat up while I boil that as soon as it's boiled I'm gonna
empty these pour the boiling hot water in them and in 12 hours I'll put a
cooking thermometer in there and see which one is hottest and when I get the
boiling water filled up in these thermoses I will show you what time it
is on my stove and then 12 hours from now I'll recheck it okay I got a good
boil going here and we know water boils at 212 degrees so I'm gonna empty these
pour the boiling water in them and we'll see I said 12 hours I that would mean I
have to get up at like 2:00 or 3:00 in the morning I'm not gonna do it so we'll
call it like let's say 9 hour yeah 11:42 say what midnight right at midnight
I'll check the temperature and I'll record the difference in temperature
between the two thermoses okay
okay I can't do a I can't do this with one hand so I'm gonna have to shut this
off and fill them up with the boiling water okay I'll see you here at midnight
okay it's like nine minutes away from being nine full hours yeah let's go to
Walmart to buy a thermometer I tore this house apart looking for my thermometer
well let's get to it nine hours
let's say that's right at 184
unbelievable and all those years couldn't figure out what my coffee was
always cold
it's like 130 like right at 130 so what a huge difference 54 degrees difference
I'm sold I'm glad I bought that that's a thermos by Nissan and that's an old
Stanley when they used to make them in the United States they don't even make
them in the United States anymore and the new ones don't even have any kind of
insulation this is the old one that has like some sort of charcoal insulation in
between the inner and outer portion and this is something called Thermax
insulation and all day long I've been going by this and you can put your hand
on it and it felt warm on the outside and this did not that's where the heat
escapes on the outside when you're driving down the road in a truck and you
sent your thermos on the floor and it's winter that thing I'd get three or four
hours out of that hot coffee and this one oh eight or nine hours sitting on
the floor and a coffee and still be hot okay that's my comparison
