|Hang on to those little pop-up turkey timers this holiday season |
to throw in your survival kits and bug out bags to use as WAPIs!
Just to demonstrate the effectiveness of the pop-up turkey timer
as a water pasteurization indicator (WAPI), we decided to photo
document the process on our indoor stove top so that you can see
how well it really works!
Here we start with a pot of hot tap water on the
stove top with the pop-up turkey timer floating in the water poised
to go off once our water hits our pasteurization temperature. We
also make use of a thermometer to show water temperature as we
progress! As you can see here, our water is at typical "hot" tap
water temperature at about 120° F (48° C).
As you can see via our thermometer, our water has risen in
temperature to slightly over our actual required minimum
pasteurization temperature of 149° F (65° C) where all
living organisms are killed quickly. We are now at 160° F
(71° C) which is the accepted industry standard used to
pasteurize milk and various other food/drink products. But as
you can see in the photo, our pop-up turkey timer still hasn't
activated yet. It hasn't "popped". So does this mean that our
experiment is a failure? Not so fast!
Look! Our pop-up turkey timer popped! Let's take a look at
the thermometer and see what temperature our water is now!
As you can see, our water temperature is now slightly under
170° F (76° C). Now this is slightly higher than the
temperature we need for water pasteurization, but it's still 42°
less than the 212° F (100° C) required to boil water! That is
a huge fuel and time saver!
Remember... we don't need this timer to show us that we are
precisely at pasteurization temperature (149° F/160° F or
65° C/71° C depending on your personal preference in
pasteurization standard). We only need a reliable indication
that we have AT LEAST reached pasteurization temperature.
That being the case... mission accomplished!!
Now here's aspect of these pop-up turkey timers
that very few people are aware of: They are
reusable! We are going to demonstrate how to
As you can see, I am holding the activated timer
in my hand. I simply dipped the tip of my little
timer back into my pot to soften the soft metal or
wax that holds the blue indicator in place until it
softens enough from heat to allow the internal
spring to "pop" the indicator out. Once the tip of
our turkey timer has been reheated, I push the
blue indicator back in.
Once the blue indicator is again depressed, I then
run the tip of our timer under cold water to cool
the metal or wax so that it once again retains
the blue indicator.
As you can see, our improvised pop-up turkey
timer water pasteurization indicator has been
reset and is ready to use again!
