Make every cake of soap last twice as long

To make a cake of soap last twice as long, simply paint the top or bottom with some PVA wood glue and let dry. Doing this means only one side of the soap dissolves, enabling the cake to last double the time. I paint the top side of the cakes of soap when we bring them home. Sometimes my granddaughter even glues a pretty picture to the side!

Lock in fuel savings and make them last!

Our household has found a super easy way to make the most of cheap fuel prices. We watch the fuel cycles with the ACCC petrol price cycles website (https://www.accc.gov.au/consumers/petrol-diesel-lpg/petrol-price-cycles). When it is getting to the lowest point of the cycle, as well as our vehicle, we also fill up five 20 litre fuel containers. If it is inconvenient to do so, we prepay and lock in the fuel price on both of our phones on the 7/11 app. This guarantees that locked price for seven days. We then use that fuel through the next 3-4 weeks (the length of the fuel cycle generally). It's like having our own petrol station at home!

Fuel containers cost around $20-$25 at BCF and the savings per cycle paid for each container. Now it's pure savings of $30 per cycle. Petrol works out around $520 per year less for us, for very little effort! At first, my husband was concerned that the fuel may not last (he is a qualified mechanic), but I showed him some tests BP had done on this matter, finding that six months later, the values were still the same. We notice zero difference in fuel consumption, km/L, or parts wearing out any faster.

Everyone we tell thinks this is an amazing idea, we find it strange that no one else seems to have thought of it!

Make baby fruit gels at home

If your baby or toddler enjoys Heinz fruit gels, you can easily make your own at home. The benefit is that you know exactly what you are feeding them and it costs you a lot less! You will need:

2 cups of fruit juice (apple, blackcurrant or whatever you choose)
1/2 teaspoon Agar powder (you can buy this from health food shops; don't be put off by the cost as it will last a long time). You need to measure the ingredients exactly to get the right consistency, otherwise the gel will be either too firm or too runny.

Put the juice in a saucepan and bring to the boil. Then sprinkle the Agar over the top and let simmer for about 30 seconds. Pour into jars or containers and let set in the fridge. This should make around eight serves depending on the size of the containers. Unlike gelatin, Agar will stay firm if the gel is taken out of the fridge. You can also mix pureed fruit like apple, and it won't affect the recipe. For toddlers or older children you can mix two fruits and it is just like the jelly fruit cups you buy in the supermarket.

Get your food free all the time

When I separated from my husband and was left with three children, I had no income apart from the pension. Food was getting very scarce, so I had to become creative. Every second week I drove to Flemington fruit and vegetable markets in Sydney (about closing time when most food is the cheapest), bought food by the boxes, and spent the whole day processing it. I made vegetable lasagnes, which I would freeze, all sorts of sauces, vegetable selections for stir frying and steaming, mango ice blocks (pureed mango only) and so on. We would use the most perishable fruit and vegetables the first week and the others later. Eventually we started to have an overabundance of food.

Then I told a few friends of my system, and very soon I was running a little co-op. I started to go to the markets every week and buy a greater variety of food. I got my fruit and vegies free and could also split up my petrol bill for the week amongst participants of the co-op. They got their food much cheaper than in the shop, and I got my food and petrol free.

Apart from that we had the freshest food, with fresh fruit or vegetable juices every day. Out the window went fizzy drinks and any convenience foods. It is now about 14 years since we started to eat like this, and we don't even have a family doctor, because we hardly ever get sick. How much we saved on medicines I cannot even begin to calculate.
