If you need a hot
water bottle in a hurry, there usually isn't time to take
a trip to the drug store to buy one. Instead, you can make
your own.
Take an empty 2
litre plastic bottle that soft drinks come in (be sure it
is cleaned well). Fill it with hot (but NOT boiling) water.
Then wrap in a towel and use as a hot water bottle.
This is a quick
trick if you need a hot water bottle to treat a strained muscle,
tummy ache or PMS symptoms.
