One of the largest sources of carbon dioxide that contributes to our domestic carbon footprint comes from heating our homes. We can reduce this part of our carbon footprint by turning down the heating in our homes and/or reducing the number of hours we have the heating on. Of course it is important that we don’t get cold. We can keep warm by wearing extra layer of clothes and by taking regular exercise. Today’s activity is a nice extra – a hand warmer.
For this you will need a piece of cotton fabric – about 14x28cm. Fold this in half with the pattern on the inside. Sew the fabric together alone two sides.
Turn the fabric right side out so that the rough edges are inside what is now a pocket.
Fill the pocket with uncooked rice. Use a sheet of paper to make a funnel so that you can more easily pour in the rice. Fill about half full.
Tuck the unseen edges inside and stitch the sides together. Use small stitches so that the rice can’t escape.
To use the hand-warmer, place in a microwave and heat for a minute. It should be warm to hold.
You can reuse the hand-warmer several times but do be careful: over time the rice will bake and might eventually burn and scorch the hand-warmer.
