3 Ways to Make Ice Cubes without a Shape

Without a form of ice, chilling drinks quickly in that heat may seem almost impossible, but it isn't! There are several ways to make ice cubes without using the traditional molds. You can use silicone molds, use an egg carton as a makeshift mold, or make crushed ice in a plastic bag. As long as you have a freezer, these common household utensils will allow you to make ice cubes that will work just as well as the ones made in the molds.


Method 1 of 3: Using a Silicone Mold

Make Ice Cubes Without a Tray Step 1

Step 1. Choose a shape that will hold water easily and without spilling

If you have a mold made of silicone that is rigid and deep enough for the water to stay where it should as you move it, it will serve as an ice cube tray. The best molds are the ones that have square or round shapes, but the ones in the form of designs will also work.

Since silicone molds are often used to make sweets such as chocolates and lollipops, each “ice cube” will have the shape of the silicone design

Step 2. Fill the spaces with water

Turn on the faucet and place the mold under it until all spaces are filled with water. Don't let water build up over the spaces, as this will form a thin layer of ice on top of your "cubes". Try to hold the shape with your hand under it so it doesn't bend or let the water leak out.

You can leave some space between the edge of the holes and the water level if you want to make sure that thin layer of ice doesn't form on top

Step 3. Take the molds to the freezer and leave for at least four to eight hours

To be able to freeze the entire water, the ice cubes will have to stay in the freezer for at least several hours. If you want the cubes not to break or melt easily, let them freeze for at least eight hours. Leaving it overnight is a great way to ensure rock hard ice.

Step 4. Twist the ice out of the pan, just as you would a regular ice pan

Since silicone is soft, it will bend a little, allowing the ice to come off easily. You can also turn the shape on the other side so the ice cubes that are loose fall down. Do not use too much force or bend the shape too much or it may break or become damaged.

Insert the opposite side of a fork or spoon between the ice and the pan if it is difficult to release the ice

Method 2 of 3: Making Ice in Plastic Bag

Step 1. Fill ¼ of a plastic bag with water closure

Place the open plastic bag under the faucet and let it fill until it reaches ¼ of its capacity. You can use any size plastic bag. Bigger ones will yield more ice because they have more room for water. No matter what the size of the plastic bag, do not exceed the ¼ capacity mark. Never fill to the mouth.

You can use plastic freezer bags or thinner ones for sandwiches to make ice

Step 2. Close the plastic bag to keep water inside

Once you have filled ¼ of its capacity with water, close the plastic bag by pressing the two parts of the clasp together. If you don't close it, the water will leak into the freezer, so close it properly.

Leave a little air inside a plastic bag to make it easier to remove the ice after it breaks. You just need enough air so that the top of the plastic bag doesn't press into the water

Step 3. Place the plastic bag on its side inside the freezer

To create a layer of ice that's easy to break or crush, you'll have to freeze the water horizontally in relation to the plastic bag. Put it straight on the straightest surface you have in your freezer.

  • The straightest surface will likely be the freezer floor, as, on top of the crates, the bag can become uneven and form an irregular block of ice.
  • If you are concerned about water leaks, place the plastic bag on top of a tray or inside another plastic bag.

Step 4. Freeze the water inside the plastic bag for four to 12 hours, depending on the amount of water

A small plastic bag will freeze in about four hours, but a large one can take eight to 12 to freeze long enough for you to be able to break the ice without it melting too quickly. The more water, the longer it will take to freeze.

The longer waiting time is due to the fact that the water has to freeze in one block instead of freezing in separate pieces

Step 5. Take the ice out of the freezer and break it

You can break the ice with your hands into small, thin cube-like pieces, or you can simply take a rolling pin and crush the block. If you exceeded ¼ of the plastic bag's capacity when you filled it with water, then you'll have to crush the ice because it won't form a thin, easily peelable layer.

Do this while the ice is still in the plastic bag so it doesn't make a mess

Method 3 of 3: Improving an Ice Shape in the Egg Carton

Make Ice Cubes Without a Tray Step 10

Step 1. Buy an egg carton made of Styrofoam to have a simple waterproof ice cube tray

If the eggs you usually buy come in Styrofoam boxes, then you already have the perfect alternative ice form. Styrofoam is almost completely waterproof and the water will freeze without sticking to the Styrofoam as it would if the box were made of cardboard.

Wash the box thoroughly beforehand to get rid of microorganisms that cause food poisoning, such as salmonella

Step 2. Line the egg carton with aluminum foil if it is not Styrofoam

If the egg cartons on the market are all cardboard, you can still use them to make ice cubes. Take a sheet of aluminum foil and tear it into squares to place in the spaces in the box. As long as the aluminum doesn't crack, it will create an impermeable barrier between the water and the cardboard.

  • Do not leave any gap between the box and the water by using square aluminum pieces and placing them in the middle of the spaces where the eggs are, so the lining is perfect.
  • It's a good idea to leave the aluminum above the spaces to make it easier to remove the ice later.

Step 3. Fill the spaces with water

Take your styrofoam or cardboard-lined egg carton and fill the spaces with tap water until you reach just below the rim. If you overfill it, the water will leak and fall into the other holes. The ice will form half circles in the box.

Do this even more carefully if the box is made of cardboard, as these leaks will soften the paper

Step 4. Place the egg carton in the freezer for four to eight hours, without capping

Do not let the egg carton lid cover the water-filled holes, as this can slow down the freezing of water. Ice needs at least four hours to solidify and at least eight hours (or overnight) to be able to not melt fast or break.

You can also remove the lid from the box before taking it to the freezer

Step 5. Take the ice out of the egg carton by squeezing from underneath

Pinch under each hole to press on the ice and help it out of the box. If it's cardboard, you may be able to simply pull out the aluminum foil, depending on the condensation that has formed between the aluminum and the cardboard.
