You will have to do a lot of things on your own when the zombie apocalypse is in full swing. Here is one handy DIY item that you can put together in a jiffy. It's called an Everlasting Crisco Candle and it is just the thing you need for emergencies. All you need to put this candle together is a Crisco can and a few wicks. The number of wicks you insert will depend on the diameter of the candle. So, greater number of wicks can be inserted in the Criso can if it has a larger diameter. Also, make sure that about half inch of the wick juts out of the candle. Just even out the Crisco on top in the end and the candle is ready for use.
