Getting two plastic containers unstuck can be a frustrating experience. Luckily, there are several methods to try. One method involves using hot and cold water: place the containers in a sink or bathtub, cover half of the outside container with hot water, and fill the inside container half-full with cold water and ice. Wait a few minutes, then try to pull the containers apart. Alternatively, you can try using oil: soak some paper towels in a light vegetable oil, such as canola, and place them around the seam of the containers. Let the oil work its way through the seam. If you're in a hurry, WD40 will work faster, but it's not food-safe. Finally, you can try the freeze method: lay the containers on their sides in the freezer for a few minutes, then try to wiggle them apart.

What You'll Learn
Use hot and cold water
One effective method for separating stuck plastic containers is to use hot and cold water. This method works because cold causes materials to contract, while heat causes them to expand.
First, place the containers in a bathtub or sink. If your containers are small enough, you could also place them on a surface outside, such as a grassy area. Next, fill the sink, tub, or container with enough hot tap water to cover half of the outside container. Be sure to only fill the outside container halfway, as you will also be adding cold water to the inside container.
Now, pour ice and cold water into the inside container until it is half-full. Again, make sure the container is only half-filled to avoid overflowing when you try to separate the containers. Wait two to three minutes, allowing the hot water to heat and expand the outside container, and the cold water to cool and contract the inside container.
Finally, pull the containers apart. You may need to wiggle them a little to help them come apart. If they do not come apart easily, you can try leaving them for a little longer, or you could try hitting the stuck seam carefully with your hand or on a table corner.

Try vegetable oil
If you have two plastic containers that are stuck together, one way to separate them is by using vegetable oil. This method is particularly useful if you want to avoid getting the containers wet or exposing them to extreme temperatures.
To use this method, start by soaking some paper towels in a light vegetable oil such as canola oil. Roll up the oiled paper towels and place them around the perimeter of the containers, along the seam where they are stuck together. Keep the containers vertical to allow the oil to drip down along the seam.
The vegetable oil will slowly work its way into the seam between the containers, lubricating the surfaces and reducing the friction that is holding them together. Depending on the thickness of the oil and the tightness of the seal, this process may take several minutes or longer.
Once the oil has had enough time to work its way into the seam, you can try gently pulling the containers apart. If they still seem to be stuck, allow more time for the oil to penetrate the seam and try again. With enough patience, the vegetable oil should allow you to separate the containers without damaging them.
This method is a safe and effective way to unstick plastic containers, especially if they are used for food storage and need to remain food-safe. It may take longer than some other methods, but it is worth trying before resorting to more drastic measures that could damage the containers or compromise their food safety. So, the next time you find yourself struggling to separate two stubborn plastic containers, don't hesitate to give the vegetable oil trick a try!

Hit the containers against a surface
If you have two plastic containers that are stuck together, hitting them against a surface may be an effective way to separate them. This method works on the principle that sometimes, a sharp impact is all that is needed to dislodge the seal between the containers.
To begin, place a towel or a soft cloth on a stable surface to protect the containers from scratches or damage. You can also do this on a grassy area outside to avoid any potential damage to your containers or the surface beneath. Place the stuck containers on the prepared surface, with the seam where the containers are joined facing upwards. This will allow you to target the impacted area directly.
Using a gentle tapping motion, start hitting the containers against the surface. You can adjust the force of your taps as needed, but it is generally advisable to start with a lighter force and gradually increase it if necessary. The goal is to apply enough force to dislodge the seal without damaging the containers. You can also try hitting the stuck seam with your hand or on a table corner carefully.
If the containers do not separate after a few attempts, you may need to try a different method or combination of methods. For example, you could try placing the containers in hot water for a few minutes before trying the hitting method again. The hot water will cause the plastic to expand, and the sudden change in temperature might help loosen the seal. Remember to exercise caution when handling hot water and containers to avoid any burns.

Put them in the freezer
If you have two plastic containers that are stuck together, one way to separate them is by utilising the contrasting effects of hot and cold. This method involves placing the containers in the freezer.
First, place the containers on their sides in the freezer for a few minutes. By positioning them on their sides, you prevent one container from following the other as it shrinks due to the cold temperature. This ensures they don't remain wedged together.
After a few minutes, attempt to gently wiggle the containers apart. The cold temperature causes the plastic to contract, making it easier to separate the containers. If they are still stuck, leave them in the freezer for a little longer and try again.
It is important to note that this method assumes the containers are dry. If they are wet or damp, the water inside them may freeze, preventing the necessary contraction and expansion effect. In such cases, it might be more effective to use the hot water method, where you submerge the containers in hot water, causing the outer container to expand and allowing them to be pulled apart.
By using the freezer method, you can take advantage of the principle that cold temperatures cause materials to contract. This contraction will create some wiggle room between the containers, allowing you to separate them with a gentle force. Remember to handle the containers with care to avoid any damage or breakage during the process.

Soak in warm, soapy water
If your plastic containers are stuck together, one way to separate them is to soak them in warm, soapy water. First, place the containers in a sink or bathtub, depending on their size. If you're dealing with smaller containers, the sink should be sufficient, but for larger containers, you may need the extra space of a bathtub. Make sure the containers are lying on their sides—this is important because it allows for the expansion and contraction of the containers without them staying wedged together.
Next, add enough warm tap water to the sink or tub to cover at least half of the outside container. Warm water is ideal because it will help to gently heat up the containers and encourage them to expand, especially if they were stacked when they were warm. Additionally, warm water mixes more effectively with soap, creating a soapy solution that can penetrate the seam where the containers are stuck together.
Now, add some dishwashing liquid or soap to the water. You want enough to create a soapy mixture that will help loosen the seal between the containers. The soap reduces the surface tension of the water, allowing it to more easily penetrate the tight spaces between the containers. This is similar to how oil can be used to separate containers, but soap and water are generally safer and more accessible options for most people.
Let the containers soak for a few minutes. During this time, the warm, soapy water will work its way into the seam, and the heat will cause the containers to expand. After a few minutes, try wiggling the containers gently to see if they come apart. If they don't come apart easily, you can let them soak for a little longer or try adding a bit more soap to the water.
This method is a safe and effective way to separate stuck-together plastic containers without resorting to more drastic measures like a sledgehammer! It utilizes the basic principle of heat expansion and the lubricating properties of soapy water to safely loosen the seal between the containers.
