If you love outdoor activities like camping, hiking, or picnicking, you know how important it is to keep your food and drinks cool. While cooler bags and ice packs are widely available, they can be quite expensive. Thankfully, you can easily make your own freezer blocks at home for free, using items you probably already have in your kitchen.
To make your own freezer blocks, you will need a few basic supplies: empty plastic bottles, water, and a freezer. Start by rinsing out the plastic bottles and removing any labels or residue. Fill the bottles about three-quarters of the way with water. Leave some room at the top for the water to expand as it freezes. You can also add a drop or two of dish soap to help prevent the water from becoming cloudy as it freezes.
Next, tightly screw the caps back onto the bottles. Make sure they are secure to avoid any leakage in the freezer. Place the bottles upright in your freezer, making sure they won’t tip over. It’s important to position them in a way that allows airflow around them for quicker freezing. Leave them in the freezer for at least 24 hours, or until the water is completely frozen.
Once your freezer blocks are frozen solid, they are ready to use. Simply remove them from the freezer and place them in your cooler bag or picnic basket alongside your food and drinks. The freezer blocks will slowly release their coldness, keeping your items cool for an extended period. They can be reused multiple times, just make sure to refreeze them after each use.
With homemade freezer blocks, you can enjoy your outdoor adventures without worrying about the high cost of commercial ice packs. Plus, you have the added bonus of knowing exactly what’s inside your freezer blocks, ensuring they are safe and free from any harmful chemicals. So the next time you plan a picnic or camping trip, save some money and create your own freezer blocks for a hassle-free cooling solution.
Prepare the Materials
Before you can make your own freezer blocks, you will need to gather the necessary materials.
Here is a list of what you will need:
- A plastic container with a tight-fitting lid. The size of the container will depend on how large you want your freezer blocks to be.
- Distilled water. Using distilled water is important because it lacks impurities that could affect the quality of the freezer blocks.
- A freezer. This may seem obvious, but make sure you have enough space in your freezer to accommodate the container(s) you are using.
- Food coloring (optional). If you want to add some color to your freezer blocks, you can use food coloring. This step is entirely optional and is only for aesthetic purposes.
Choosing the Right Container
When choosing a plastic container, there are a few things to keep in mind. Firstly, make sure the container is freezer-safe. Some containers may become brittle or crack when exposed to low temperatures.
Secondly, opt for a container with a tight-fitting lid. This will ensure that the water does not leak out and create a mess in your freezer.
Lastly, consider the size of the container. If you require small freezer blocks, you can use small containers or even ice cube trays. If you prefer larger freezer blocks, choose a larger container accordingly.
Instructions
- Clean the plastic container with warm, soapy water and rinse it thoroughly to remove any residue. This will prevent any unwanted odors or flavors from affecting the water in your freezer blocks.
- If you want to add color to your freezer blocks, add a few drops of food coloring to the bottom of the container before filling it with water. Mix the food coloring around using a spoon or stir stick.
- Fill the container with distilled water, leaving about an inch of space at the top to allow for expansion as the water freezes.
- Securely place the lid on the container.
- Place the container in the freezer and allow the water to freeze completely. This can take several hours or overnight, depending on the size of your container and the temperature of your freezer.
Once the water is completely frozen, your homemade freezer block is ready to use!
Gather the Necessary Supplies
Before you can start making your own freezer blocks, you will need to gather the necessary supplies. Here are the items you will need:
1. Plastic containers
You will need plastic containers with lids to hold the mixture that will become the freezer blocks. Make sure the containers are clean and free of any cracks or holes. You can use any size or shape container depending on your preference.

If you prefer to use a rubbing alcohol solution, combine equal parts rubbing alcohol and distilled water in a bowl.
Once your mixture is ready, carefully pour it into the containers. Be sure to leave some space at the top to allow for expansion during freezing. Avoid filling the containers to the brim as the mixture will expand and may cause the containers to burst.
Seal the containers tightly with their lids to prevent any leakage during freezing. Make sure the lids are secure and do not cross-thread them.
Place the filled containers in the freezer in an upright position to allow for even freezing. Leave them undisturbed until fully frozen, which usually takes around 24 to 48 hours depending on the size and temperature of your freezer.
Once the freezer blocks are completely frozen, they are ready to use. Simply remove them from the freezer and place them in your cooler or lunchbox to keep your items cool and fresh for hours!
Freeze the Blocks
Once you have filled your containers with the gel mixture, it’s time to freeze them. Place the containers in the freezer and make sure they are standing upright to prevent any spills or leaks. It’s also a good idea to label the containers with the date and contents, so you can keep track of how long they have been frozen and what gel mixture they contain.
Leave the containers in the freezer for at least 24 hours or until the gel mixture is completely frozen. The freezing time may vary depending on the size of your containers and the temperature of your freezer. It’s important to make sure the freezer is set to the coldest temperature for optimal freezing results.
Once the gel mixture is frozen solid, carefully remove the containers from the freezer and check to make sure they are completely frozen. The blocks should be firm to the touch and have no liquid or slushiness inside. If the blocks are not completely frozen, place them back in the freezer for a few more hours.
Once the blocks are fully frozen, they are ready to use! You can now place them in your cooler or lunchbox to keep your food and drinks chilled. Remember to always keep the blocks in contact with your perishable items for maximum cooling effect.
When you are finished using the freezer blocks, simply return them to the freezer for future use. They can be reused over and over again, making them a cost-effective and environmentally-friendly alternative to store-bought freezer packs.
