A candle is not as obsolete as you may think. These ignitable wicks embedded in flammable wax can come in handy for those unlikely circumstances you don't have a flashlight available to use. Anyway, to create your own makeshift candle lantern you need to make some coverage for your candle first , an empty soda can should do. Now, grab the soda can and cut it open with a switchblade through one of its sides, next, bend the cut layers outwards and put inside the candle like is shown in the following image : Of course, you need to fit the candle inside. The can layers should provide enough protection from elements like air or rain, therefore your flame will linger with ease.
