Stuck plastic containers can be frustrating to separate. The longer they remain stuck together, the harder it will be to separate them. There are several methods to separate two plastic containers that are stuck together. One common method is to use the difference in thermal expansion of the two containers by filling the inner container with cold water and the outer container with hot water. This causes the inner container to contract and the outer container to expand, making it easier to separate them. Another method is to use an air compressor to pump air between the containers to break the vacuum. If the containers have handles, you can also try stepping on the handle of the inside bucket, grabbing the collar of the exterior bucket, and twisting and pulling them apart.
| Characteristics | Values |

What You'll Learn
Use hot and cold water
If you have two plastic containers stuck together, one effective method to separate them is to use hot and cold water. This method takes advantage of the fact that objects expand when heated and contract when cooled.
First, fill the inside container with ice and cold water. Then, place the outside container under hot running water or dunk it in a sink or tub filled with hot water. Make sure that the hot water doesn't touch the inner cold container. Within 20 seconds to a few minutes, the outer container will expand, and the inner container will contract, allowing you to pull them apart easily.
Alternatively, you can try the reverse process by filling the inside container with hot water and dunking the bottom of the outside container in ice water or wrapping it with a freezing-cold towel. This will cause the inner container to expand and the outer container to contract, making it easier to separate them.
It's important to note that this method may take some time and patience. Be cautious when handling hot water, and avoid using excessive force when pulling the containers apart to prevent damage or injury.
If the containers are particularly difficult to separate, you can try alternating between hot and cold water treatments or combining them with other techniques, such as using a wooden skewer or your fingers to gently apply pressure and pry the containers apart. Remember always to prioritize safety when attempting to separate stuck containers.

Try vegetable oil
If your plastic containers are stuck together, vegetable oil can be used as a lubricant to help separate them. This is because the containers may have become stuck due to moisture or friction, and oil can help to reduce the friction between the two containers.
To use this method, start by placing the containers in a sink or outside on the grass, laying them on their sides. Then, pour a small amount of vegetable oil around the rim of the bottom container. Rotate the containers while pouring the oil to ensure that all sides are lubricated. Allow the oil to work its way between the containers for a few minutes. You can also try gently twisting the containers to help the oil penetrate the seal.
Once the oil has had time to work, carefully pull the containers apart. Be gentle and avoid using excessive force, as this may cause the plastic to crack or break. If the containers are round, you can try rolling them back and forth on the counter until they come apart.
After separating the containers, be sure to wash them with a mild dishwashing detergent and dry them with a cloth to remove any excess oil.

Poke a nail hole
If you want to separate two plastic containers by poking a nail hole, you can try the following methods:
Using a heated nail
One method is to use a heated nail to melt a hole through the plastic. Hold the nail with pliers, preferably the vice-grip kind that locks into place, and heat it up with a lighter or stove. Then, poke the nail through the plastic where you want the hole to be. Make sure to do this over a concrete or other solid, non-flammable surface, and be careful not to start a fire. After creating the hole, wash the container to remove any toxins from heating the plastic and rub the inside of the hole with your finger to smooth out any sharp edges.
Using a drill
Another option is to use a drill with a small bit to create the hole. You can draw the hole pattern on paper, tape it to the container, and then drill slowly to avoid cracking the plastic. If you don't have a drill, you can try holding the drill bit with pliers and heating it up before melting the hole through the plastic.
Using a soldering iron
If you have access to a soldering iron, you can use it to make holes in plastic containers. The benefit of using a soldering iron is that you can control the size of the hole by adjusting the pressure and temperature.
Using a screwdriver
If you don't have access to a drill, you can also use a screwdriver. Heat the screwdriver on a stove or another fire source and then gently twist it in circles to melt the plastic and create a hole. Make sure to do this outdoors to avoid inhaling the fumes.

Apply dish soap
If your plastic containers are stuck together, one way to separate them is by applying dish soap. This method is especially useful if the containers are stuck due to moisture or friction.
First, fill the bottom container with hot water. You can do this by placing the containers in a kitchen sink filled with enough hot water to come halfway up the bottom container. Alternatively, if the containers are small, you can fill the bottom container with hot tap water in the sink or bathtub.
Next, pour cold water or ice water into the top container until it is about halfway full. If you are using ice water, you can add a few ice cubes as well. This will help increase the temperature difference between the two containers, making the method more effective.
Let the containers sit for a few minutes. The hot water will cause the outer container to expand, while the cold water will make the inner container shrink, creating a gap between the two.
Now, it's time to apply the dish soap. Pour or squirt a generous amount of dish soap between the containers, all the way around or close to the rim. You can also try running the dish soap along the edges where the containers are stuck. The dish soap will act as a lubricant, making it easier to separate the containers.
Finally, gently twist and pull the containers apart. You may need to work the containers back and forth or in a corkscrew motion to loosen the seal. If the containers are round, you can try rolling them back and forth on the counter until they come apart.
Remember to wash the containers with a mild dishwashing detergent and dry them with a cloth after separating them to remove any soap residue.

Use a mallet or hammer
If you are unable to separate two plastic containers, one method you can try is using a mallet or hammer. This method works best for containers that are tightly wedged together. The impact of the mallet or hammer creates vibrations that can help loosen the seal between the containers.
To use this method, first, try to gently tap around the edges of the top container with a rubber mallet or the handle of a screwdriver wrapped in a cloth. Be careful not to use excessive force, as this may damage the containers. The gentle tapping should create vibrations that can help break the seal.
If you do not have a rubber mallet, you can also use a regular hammer or mallet, but it is important to exercise caution. Place a cloth or towel between the hammer and the container to avoid leaving marks or causing damage. Gently tap the cloth-covered hammer around the edges of the container, creating vibrations that will help loosen the seal.
Once you have tapped around the edges and created some movement between the containers, you can try prying them apart with your hands. Place your fingers in the gap between the two containers, with the pads of your fingers against the bottom container and your thumbs against the top container. Gently pry the containers apart, being careful not to apply too much force.
If the containers are still difficult to separate, you can try placing them in a sink or bathtub and covering them with hot water. The hot water will help loosen the plastic, making it easier to separate the containers. You can also try using a hairdryer on a low or medium setting to apply heat to the edges of the containers. Once the plastic feels slightly warm, gently pull the containers apart.
