Five-gallon buckets can be difficult to separate due to the vacuum or negative air pressure created when trying to pull them apart. Applying force to separate them increases the negative pressure, making the task even more challenging. Various methods can be used to overcome this issue, such as equalizing pressure by warming the buckets, using lubrication, or drilling a small hole in the bottom of one bucket to release the vacuum. Other suggestions include using an air compressor, stepping on the handle of the inner bucket while twisting and pulling, or employing a combination of hot water, soap, and tools like screwdrivers or a hammer.

Drilling a hole
Next, you will need a drill and a suitable drill bit. If the bucket is made of hard plastic, a regular drill bit should work. However, if the bucket is made of thicker or more durable plastic, you may need a stronger drill bit, such as a diamond bit. Place the drill bit into the drill and position it at a 90-degree angle to the marked spot. Start drilling slowly and with light pressure to avoid cracking the plastic. Once the hole is drilled, you can use an air compressor or compressed air to force air between the buckets and separate them.
If you do not have an air compressor, you can try using a flat-head screwdriver to pry between the buckets and create some space for air to enter. You can also try lubricating the area around the hole with oil or soap to help the buckets slide apart more easily. It is important to note that drilling a hole may not be suitable if you intend to use the bucket for liquids, as the hole will create a leak.
Additionally, if you are concerned about the appearance of the bucket or want to prevent leaks, you can plug or seal the hole after separating the buckets. This can be done by using a screw, RTV silicone, or another suitable material to fill and cover the hole. Overall, drilling a hole is a straightforward and effective method to separate stuck 5-gallon plastic buckets, but it may not be suitable for all situations, especially if you need the buckets to be watertight.

Using hot water
First, ensure you have a container large enough to submerge the bottom bucket. If you don't have a container that size, you can try pouring hot water into the interior bucket and rotating it for even coverage.
Next, fill the larger container with very hot, but not boiling, water. Submerge the bottom bucket in the hot water and let it sit for around 30 seconds to a minute. The exact time will depend on the material of the buckets and how long it takes for the plastic to expand.
Once the bottom bucket has been heated, remove it from the hot water. You can now try to separate the buckets by pulling them apart. If they don't come apart easily, you can enhance the effect of the hot water by filling the uppermost bucket with ice water. The simultaneous expansion of the bottom bucket and contraction of the top bucket due to the temperature difference should help break the vacuum seal.
If the hot water method doesn't work, there are other options to try. One suggestion is to use compressed air, either by blowing it into the joint between the buckets or by drilling a small hole in the bottom of one bucket and applying air directly. Another option is to use a screwdriver or flathead screwdriver to pry between the buckets, or to tap the buckets gently with a hammer.

Applying soap
First, try to drip soapy water or dish soap between the buckets. This will help to loosen the seal and break the vacuum that is keeping the buckets stuck together. You can also try to fill the gap between the buckets with soap by using a spray or by drizzling it in.
If you have access to an inner bucket, you can fill it with hot water and rotate it to get as much coverage as possible on the inner surface of the outer bucket. This will help to warm up the plastic and make it less brittle, making it easier to separate the buckets.
Once the soap has been applied and the buckets have been warmed, you can try to separate them by hand. Hold the bottom bucket between your feet and grab the top bucket with your hands, then pull and twist the buckets in opposite directions. You can also try stomping on the inner bucket and rotating it slightly with each stomp to loosen the seal.
If the buckets are still difficult to separate, you can try using a tool such as a flathead screwdriver or a filet knife to pry between the buckets and equalize the air pressure. Alternatively, you can try to drill a small hole in the bottom or side of one of the buckets to let air in and stop the vacuum. However, this may not be suitable if you intend to use the buckets for liquids.
By following these steps and combining the application of soap with other separation techniques, you should be able to successfully separate two 5-gallon plastic buckets that are stuck together.

Twisting and pulling
Using your hands and feet
Place the buckets on their sides, sit on the outer bucket, and pull and twist the inner one. You can also try the opposite—place your foot on the handle of the inner bucket and pull the outer bucket with your hands, twisting as you pull. If you have a friend to help, you can each grab a bucket and twist and pull in opposite directions.
Using tools
If the buckets have handles, turn them upside down and step on the handle of the inside bucket. Grab the collar of the exterior bucket and twist and pull. If the buckets don't have handles, you can try the "hot water treatment". Run the outer bucket under hot water for 30 seconds to a minute, then twist and pull.
Other methods
You can also try to equalize the pressure by warming the buckets and the air inside. As the air molecules heat up, they move faster and bounce against the buckets, reducing the negative pressure. However, this method may cause the plastic to expand, making it more difficult to separate the buckets. Alternatively, you can try to drip soapy water between the buckets as you twist and pull, as this will help to loosen the seal and break the vacuum.

Using a screwdriver
To start, you can try to pry the buckets apart with a screwdriver. This will create a small gap between the buckets. If you have access to compressed air, you can then use the screwdriver to guide the air hose into the gap between the buckets. Blowing compressed air into the gap will push the buckets apart.
Alternatively, you can use a flat-head screwdriver to pry around the upper ridges of contact between the buckets. This method may be more effective if you first warm the buckets with hot water, as they will be less brittle and easier to separate.
If you do not have access to compressed air, you can try to wedge a flat-head screwdriver between the top edge of one bucket and the rib of the other. This method may work better if you first rinse the buckets with water to provide some lubrication.

Frequently asked questions
There are several ways to separate stuck-together 5-gallon plastic buckets. One way is to use a high-pressure hose nozzle and let the air flow in between the buckets.
You can use a screwdriver to pry the buckets apart. Spraying a lubricant, such as TDL Dry Lube, between the buckets can also help.
Yes, you can try using your body weight to separate the buckets. Turn the buckets upside down, place one foot on the handle of the bottom bucket, and pull the top bucket while wiggling it. Alternatively, you can try to equalize the pressure by warming the buckets and the air inside, as heating the air molecules will cause them to move faster and reduce the negative pressure.
To prevent the buckets from getting stuck, place a few sheets of newspaper between them when stacking.
