A Waterless Hot Water Bottle

A Waterless Hot Water Bottle
When I was a kid, winter beds were warmed with a hot water bottle wrapped in a towel.

This worked okay, but inevitably the towel slipped off during the night and the water would slowly chill. It wasn't unusual to wake in the early morning hours with a cold rubbery slab at your feet—not exactly comforting.

Microwaveable rice bags stay warm and don't slip around. I thought I would make a rice bag that's a tribute to the old-fashioned hot water bottle. It's a simple project that can be done in an hour.

Bonus: if you applique a heart onto the bottle, you can give it as a Valentine to someone you have "warm" feelings for (ouch!—sorry).

Step 1What you need

what you need
  • pattern files (.pdf files are included below, though they print out smaller than my original)
  • red fleece   Red Christmas fleece can often be found in the remainder bin in January. I was able to buy less than half a yard for $2.50—this is enough for 3 bottles. Any remnant over 11" will work.
  • scrap muslin or other cotton fabric for the inner bag
  • paper and cloth scissors—best to keep them separate
  • 2 lbs of dried rice or other grain, such as lentils or beans
  • something to sew with: needle and thread, or threaded sewing machine
  • optional: felt or ribbon for embellishment, lavender or other essence for scent

Is it safe to heat rice in the microwave over and over again? I would love to make this for my Dad (in masculine colours obviously) to help with his arthritis pain but I'm just a bit worried. Also is fleece material safe to microwave? or do you take to cotton insert out?
Please advise me

Another option is corn. I live in Iowa (Iowa=corn, right?) I go down to the local co op and ask them for a paper sack full of corn. I am willing to pay for it, but for them its like 40 cents, so every year they give it to me for free. My grandchildren love them, and they tend to over heat their corn pillows, which eventually smells like old popcorn. I've never overheated mine and it doesn't smell at all. I use two layers of flannel on each side. I usually just make a square pillow, add the corn, and sew it shut. I used to work in a nursing home, so one year I made about 20 of them. for gifts to people at work. They love theirs too, and its just old fashioned enough to appeal to elderly people. They never fail to tell me all about how they kept warm back then. I made one for my cat. She lay all over it all last winter.

My husband freeze easily (some times almost blue color) I was looking for something to use as a heating filler but never thought of rice… !!

One question though, we don’t have a microwave oven, do you think it will work with regular oven(without the fleece) if not , is there any other filling options?

Thank you in advance.

OMG THANK YOU!!!!!!! THIS SAVED MY GERBIL GALAXY'S LIFE!!!!!
I was cleaning out her and her cage-mate Maui's cage yesterday, and I found her emaciated (VERY HUNGRY/STARVING), cold, with shut eyes, an injured foot,Not walking at all, and a very visible spine. I immediately separated her from Maui and put her in a large plastic box with a towel and lots of food at the bottom. I put a heated blanket under the cage, but that didn't seem to do the trick. I was browsing instructables when I saw this. I made it in smaller version, heated it up, and went to bed.(It was about 11:30 by then.) I woke up at 6:30 this morning and expected the worst. I found Gala curled up next to it, fast asleep. I woke her up gently, and she OPENED HER EYES COMPLETELY, which had been a total improvement since the last 7hrs, GOTTEN FATTER, STARTED WALKING PROPERLY, AND WITH A MOSTLY HEALED FOOT. It was a miracle. I fear, that without this, she would have died. I owe you her life!!!!

This is so cute! I remember the leaky water bottles, this is a great idea.

Very nice! I've been using heat for a back injury but hate falling asleep on electrical cords. I made some in a different shape a few years ago and used tangerine oil scent with good feedback since not everyone likes lavender.
