What You'll Learn
Use hot and cold water
If your plastic containers are stuck together, one method you can try to separate them is by using hot and cold water. This method works on the principle of thermodynamics, where the application of heat and cold causes the plastic to expand and contract, respectively.
First, place the containers in a bathtub or sink, depending on their size. If the containers have handles, try turning them upside down and stepping on the handle of the inner container. Then, grab the outer container's collar, twist, and pull. This method uses your weight to hold one container down, making it easier to separate the two. Alternatively, if you have a friend available, you can each grasp a container and twist/pull in opposite directions.
Now, for the hot and cold water technique, add enough hot tap water to the sink or tub to cover half of the outside container. Simultaneously, pour ice-cold water into the inside container until it is half-full. Wait for two to three minutes, and then attempt to pull the containers apart. The inner container will have contracted due to the cold water, while the outer container will have expanded from the hot water, making it easier to separate them.
If you don't want to fill the containers with water, you can try simply dipping the bottom container into hot water or spraying the outside with hot water. The top container is already relatively cold, so this temperature difference may be enough to separate them.

Try the air nozzle trick
If you have two hard plastic containers stuck together, one effective trick is to use an air nozzle to separate them. This method works by equalizing the pressure between the containers, making them easier to pull apart. Here is a step-by-step guide on how to do it:
Firstly, if your containers have handles, try turning them upside down and stepping on the handle of the inner container. Grab the collar of the outer container and give it a gentle twist, then try pulling them apart. This method uses your weight to hold one container down, making it easier to separate them. If you have a friend available, you can also try having each person grasp a container and pull or twist in opposite directions.
If the containers are still stuck, it's time to try the air nozzle trick. Get an air compressor and plug it in. You may need to wait for it to pump up. Once it's ready, find a hose that will fit between the containers. Firmly hold the containers between your knees and, using the hose, blast air between the containers at the point where they are stuck. The blast of air should help to pop them apart.
If you don't have access to an air compressor, you can try using a different type of air nozzle. For this method, you will need a needle valve for inflating sports balls and a larger tapered valve for inflating vinyl rafts. First, use the needle valve to loosen the containers by inflating the space between them. Then, switch to the larger tapered valve and continue to inflate until the containers pop apart.
By using the air nozzle trick, you can effectively separate two hard plastic containers that are stuck together. This method is a quick and efficient way to solve the problem without causing any damage to the containers.

Use an air compressor
If you have access to an air compressor, this can be a quick and effective way to separate two hard plastic containers that are stuck together. Here is a step-by-step guide on how to use an air compressor to achieve this:
First, locate your air compressor and ensure it is in good working condition. Plug it into a power source and allow it to pump up and build pressure. While the compressor is building pressure, you can prepare the containers. Place the stuck containers on a stable surface, preferably in a sink or bathtub, to catch any water or debris that may be released during the process.
Once the air compressor is ready, attach a hose with fittings to the compressor. Choose a hose that is long enough to reach the containers comfortably. Then, carefully insert the end of the hose between the containers, aiming it towards the sides or the junction where they are stuck. Make sure you are wearing protective gear, such as gloves and eye protection, to safeguard against any flying debris.
Now, it's time to blast air into the junction of the containers. The sudden influx of air pressure between the containers will help to equalize the pressure and break the vacuum that is holding them together. You may need to wiggle the hose slightly to find the exact spot where the containers are stuck together.
With the air compressor still running, gently try to pull the containers apart. The air pressure should have created some space between the containers, making them easier to separate. If they still feel stuck, continue blasting air and try twisting the containers in opposite directions to loosen the grip.
Finally, once the containers are free, release the pressure from the air compressor and disconnect the hose. Rinse the containers with water to remove any dust or debris that may have accumulated during the process. Your containers should now be successfully separated!

Warm the buckets
Warming the buckets is one way to separate two hard plastic containers that are stuck together. This method works because heating the buckets and the air inside them reduces negative pressure. As the air molecules heat up, they move faster and bounce against the buckets more, reducing the negative pressure.
However, this method may not always be effective, as heating the buckets can also cause the plastic to expand, making it more difficult to separate the containers. Additionally, heating the buckets may not always be convenient or easy. If the buckets are made of heavy-gauge plastic, this method may require very hot water or may not work at all.
To warm the buckets effectively, you can try using hot water. Place the containers in a bathtub or sink, depending on their size. Add enough hot tap water to the sink or tub to cover half of the outside container. Pour hot water into the interior bucket and rotate it to get as much coverage as possible. Alternatively, you can try dipping only the bottom of the bottom bucket into hot water, as the top bucket is already relatively cold.
Another way to warm the buckets is by using a hairdryer or a heat gun. Direct the hot air towards the seam between the two containers. This will heat up the air and the plastic, potentially reducing the negative pressure and making it easier to pull the containers apart.
It is important to exercise caution when using hot water or heat guns to avoid accidental burns or melting the plastic. Additionally, always test the temperature of the water or heat gun on a small area first to ensure that it will not damage the plastic.

Try lubricating the buckets
If you have two hard plastic containers stuck together, one method to separate them is to lubricate the buckets. This method can be effective, but it may also make the vacuum problem slightly worse as you fill the space that could have allowed air to pass through.
Firstly, ensure the buckets are placed on a flat surface that can get wet, such as in a sink or bathtub. If you don't have access to a bathtub or sink, you can try placing them on a grassy area outside.
Next, choose a suitable lubricant. Water can be used as a simple and accessible lubricant. You can also try using soap—however, this may create a lot of cleanups once the buckets are separated. If you have a lubricant like WD-40 or a similar product, you can try using that, but be aware that it may be messy and could attract dirt and dust to the buckets.
Now, apply the lubricant of your choice between the buckets, focusing on the area where they are stuck together. Try to get the lubricant as deep into the seam as possible. If using water or soap, you can try pouring or spraying it into the seam. If using a spray lubricant, follow the product instructions for proper application.
Finally, firmly grip each bucket and try to twist and pull them apart. If the buckets have handles, you can try turning them upside down and stepping on the handle of the inside bucket while grabbing and twisting the collar of the exterior bucket. If you have a friend to help, you can each grasp a bucket and twist and pull in opposite directions.
