How are Wonder Warmers® better
than other heating pads?
In lots of ways! Please see
Advantages.

How do Wonder Warmers®
generate heat?
The solution in Wonder Warmers® typically freezes at approx. 130° F
(54° C). However, the pouch which holds this solution does not
provide the solution’s molecules with enough surface area to form a
crystal lattice, or in other words "to freeze". This solution can
therefore remain as a liquid even though its temperature is well
below its freezing point. By flexing the metal disk in your Wonder
Warmer® you cause a few molecules of the solution to crystallize.
These crystals in turn provide the surface area required for the
rest of the molecules of the solution to crystallize. This
"freezing" process (i.e., transition from liquid to solid) is an
exothermic chemical reaction, which releases energy and generates
heat (approx. 130° F, 54° C).

What are Wonder Warmers® made of?
Wonder Warmers® are made of a PVC pouch, which contains a small
steel disk and a solution of water and a type of salt, which is
non-toxic.

How long will my Wonder Warmers®
generate heat?
Your Wonder Warmers® will generate heat from 30 minutes to 3 hours
depending on their size and how well you insulate them.

How can I maximize my Wonder Warmers'®
heating time?
Insulating your Wonder Warmers® by keeping them in your pocket,
sleeping bag, or any other type of heat retaining wrap will prolong
their heating time. You should also knead your Wonder Warmers® after
activation to increase their temperature and keep them soft and
malleable.

How many times can I use my Wonder
Warmers®?
Wonder Warmers® can typically be used well over one hundred times.
You should be able to use your Wonder Warmer® until its PVC pouch is
punctured.

What happens if one of my Wonder
Warmers'® pouches is punctured?
If your Wonder Warmer® is punctured while it is in the liquid state
it will activate for the last time. Damaged pads should be promptly
disposed of.

What are the crystals that sometimes
appear in my Wonder Warmers®?
Crystals may sometimes form in your Wonder Warmers® due to
evaporation if they are stored in their crystal state (i.e. as
opposed to being stored in the liquid state as recommended). These
crystals will not materially impact the effectiveness of your Wonder
Warmers® and can be dissolved by boiling your Wonder Warmers® for
longer periods and allowing them to cool in water.

Why does my Wonder Warmer® crystallize
on its own shortly after I boil it?
When recharging your Wonder Warmer® you must boil it until ALL the
crystals in the pad are fully dissolved. If you still see some
crystals in the pad after you boil it, apply some pressure to the
stubborn crystals and/or boil the pad for a few more minutes to
dissolve them. If ALL the crystals are not dissolved, the pad will
self-activate as it cools.

Can I use my Wonder Warmers® as cold
packs?
Your Wonder Warmer® can be used as a cold pack. You should place
your Wonder Warmer® in the refrigerator for an hour or more to chill
it before use. However, you should not place your Wonder Warmer® in
a freezer as it will self activate.
