Summarize the following:
You don't need snow, but you need below-freezing temperatures. If the temperature is above freezing, the ice luminaries will melt too fast. Choose a day with lots of snow on the ground. The luminaries will look more magical! Stretch the opening of your balloon over the spout on your faucet. Use a regular balloon if you want a large luminary, and a water balloon if you want a small luminary. Hold the balloon to the faucet with 1 hand, and the bottom of the balloon with the other. Turn the water on and let the balloon fill until it stretches and becomes shaped like a ball.  How much you fill the balloon is up to you. The more you fill it, the bigger your luminary will become. Do not overfill the balloon; the water needs room to expand as it freezes. Turn the water off first, if you have not already. Holding the balloon in your palm, use your other hand to tug the tail off of the faucet. Set the balloon down in the sink, with the tail pointing up. Wrap the tail around your finger to make a loop, then pull the end of the tail through the loop. If you want a colored luminary, add 1 drop of food coloring to the balloon before you tie it. Shake the balloon after you tie it to mix the color. Place the balloon into the freezer, and leave it there overnight. If you live in a cold climate where temperatures fall below freezing, you can freeze the balloon outside. How long the balloon takes to freeze depends on how big it is. Expect this to take anywhere from 6 to 12 hours. Use a pair of scissors to cut the tail of below the knot. Cut the balloon apart down the sides, then peel it away from the ice. Discard the balloon when you are done. Be careful when removing the balloon. The ball may not be completely frozen inside. Depending on the size of your balloon, you may still have water inside it. If you want a solid ice luminary, you will need to freeze your balloon longer. If you want a hollow luminary, poke a hole in the ice, then drain the excess water out. Solid ice luminaries have a softer glow than hollow luminaries. Use your fingers or a small spice jar to make a shallow well in the snow. Turn on a battery-operated, LED tea light, and set it into the well. Make sure that the plastic flame is below the top of the well. If the flame is sticking out, it will get in the way of the ice ball. In this case, you should make the hole deeper.  If you make a hollow luminary, set the tea light right on top of the snow instead. If there is no snow outside, dig a hole in the soil instead. You can also use outdoor Christmas lights instead. The ones with the bigger bulbs will work better than the ones with the smaller bulbs. Because the tea light is inside the snow, the luminary should sit comfortably on top of it. There is no need to carve a hole in the luminary. If you made a hollow luminary, then make sure that you place the opening right over the tea light—you may have to break the ice around the opening to make it larger. Be aware that colored luminaries may stain your pavement as they melt.

Summary:
Ensure that it is below freezing outside. Choose your balloon and fit the opening over a faucet. Fill the balloon with water until it becomes round. Remove the balloon and knot the tail. Freeze the balloon until it turns solid. Cut the balloon away from the frozen ball. Freeze the ball longer if needed or desired. Make a well in the snow, then set an LED tea light into it. Place the luminary over the tea light.
