Maybe you are an actor or you have to show a few tears to make your story convincing; in any case, crying instantly can be a useful skill. With a little practice, you will quickly learn to cry whenever you want.
Steps
Method 1 of 3: Make your eyes look watery

Step 1. Keep your eyes open as much as possible
This will dry them out and cause them to burn. After a moment, the dryness will cause the eyes to start to water, so you should not blink until you feel the tears begin to form.
- If you are near a fan, stand still so that it blows air into your eyes, which can cause them to water.
- If you can look at a bright light, your eyes will water even faster.

Step 2. Rub them on
Close your eyes and gently rub your eyelids for about 25 seconds, then open them and stare at something until you start to water. This might take a bit of practice, but once you get the hang of it, it will work very effectively. Rubbing them can also help redden the complexion in the area around them, but don't rub them too hard as you could injure them.
Carefully place your index finger pointing towards one of your pupils. This will make the eye irritated, and may make you cry. However, try not to hurt yourself

Step 3. Bite the inside of your lip
Usually a little pain can make your eyes water, and if you need to cry instantly, you can use this tactic to your advantage. This trick will be very useful if you use it while you are thinking about something sad.
- Hold your breath as you bite into the inside of your mouth, which may focus your senses on the pain.
- You can also pinch yourself hard on a sensitive part of your body, such as your thigh or a space between your thumb and index finger.

Step 4. Apply a tear-inducing substance under your eye
Imitate Hollywood stars and apply a minty tear-inducing stick under your eyes. This may cause burning, but it will be very realistic. However, be very careful to avoid getting in your eyes.
You can also use eye drops, which will give the impression that your face has been stained with tears. Just apply them just below the corner of your eyes, so they'll look like they've run down your face, giving them a more believable appearance

Step 5. Use a chopped onion
Chopping an unwashed onion will be a very effective way to induce tears. However, this method may be better for acting, as it will be difficult to convince someone that you are sincerely crying if you take out an onion and start cutting it before doing so.
If you can go to another room, take some onion slices and smell them close to your face. Return to the conversation when your eyes start to water
Step 6. Force yourself to yawn
Yawning will make your eyes water, and if you yawn long enough, some tears will flow. Try to hide your yawn with something that covers your mouth. You can also yawn without opening your mouth, to make it more believable.
Method 2 of 3: Think of something that makes you cry

Step 1. Remember a time when you felt strong emotions
If you need to cry instantly, you can remember a time when you felt sad, helping you get into the right emotional state. For example, it may be helpful to remember the loss of a loved one or a very bad breakup.
Other emotional triggers could include the loss of something that you considered special or worked so hard for, or problems with your parents

Step 2. Imagine that you are weak or defenseless
Many people fear that deep down they are not as strong as they would like to believe. If you imagine yourself as a weak person, this could help you adopt a vulnerable mindset that can make you really cry.
- Once you embrace this feeling, you should let the feeling of being helpless express itself through your tears.
- A common exercise in acting class is to imagine yourself as a little boy who no one cares about.

Step 3. Use your imagination to create a sad situation
Sometimes remembering a bad experience from the past can generate real emotions that are difficult to overcome. If this is the case, imagine something sad that could happen, rather than something personal.
For example, you could imagine puppies abandoned by the side of the road. You want to save them all, but you can only take one. As you hold it, you will look at those you are leaving

Step 4. Cry with happiness if you don't want to feel sad
Imagine something that brings happy tears to your eyes, such as a time when someone gave you an important gift, veterans reuniting with family members, or someone overcoming adversity.
No one will know if you cry from happiness or sadness, as long as you don't smile
Method 3 of 3: Try harder to cry

Step 1. Make a crying face
This usually requires you to close your eyes and scrunch your face a little. You just have to imagine the movements you make when you really cry. If you are not sure what it looks like, you should look in the mirror, pretend that you are crying and pay attention to what you feel in the muscles of your face.
- Lower the corners of the lips a little.
- Try to elevate the inner corners of the eyebrows.
- Pucker up your chin just like people do just before crying. This could look fake if you overdo it, so be subtle.

Step 2. Focus on your breathing
Breathing is one of the things that will convince people that you are upset. He begins to sob, making crying sounds and taking deep breaths. Inhale steadily, as if you are hyperventilating. Include a small pause in your breathing every now and then to make it sound more real.
If no one can see you, run for several minutes to get out of breath. This will also help to create the flushed complexion that is often associated with crying

Step 3. Lower your head or cover your face to give it a more realistic touch
After having watery eyes, crying face and rapid breathing; You can add some finishing touches, such as covering your face with your hands, resting your head on a table, or sitting down to look sad.
- You could also bite your lip as if you are trying to stop the tears.
- Look in another direction to pretend that you are not crying, so you will fool others even better!

Step 4. Add a moan to your voice so that you sound like you're crying
The vocal cords will contract when you cry, generating the loud or whining sounds that are produced when trying to speak while crying. Stutter and include long breaths to enhance the effect.
Basically, your mind will have to force your body to do it, and the more you mimic that state, the more effectively your body will produce the effect you want

Step 5. Pay no attention to your surroundings
If you want to cry instantly, you will need to relax, breathe, and focus on why you are supposed to cry. By omitting all distractions, you can better delve into the emotions you want to express.

Step 6. Cover your face with your hands and laugh if you don't feel sad
Sometimes it can be difficult to tell if someone is laughing or crying (if they do it right). Roll your shoulders while covering your face and try to redden your eyes a bit by rubbing them hard with your hands, and don't smile when you pull them away.
- This will work most effectively on stage, as people will not be close enough to see the tears on your face in detail.
- You shouldn't make any sounds, as they might notice you're laughing! If you accidentally laugh out loud, try to make a sound similar to a moan or sob right after, but not overdo it.
Advice
- Keep hydrated. If you don't have enough water in your body, you won't be able to produce tears.
- Hold back the crying. If you have a hard time crying, sometimes you better not. Instead, give the impression that you are holding back crying. Sometimes this will move people more, especially if you tend to be more resilient. This could also be more credible, as it will give the impression that you are more vulnerable.
- Cry with a movie in which the actor is crying, so you will practice.
- Blink very fast as this will sometimes cause tears.
- Don't make it too dramatic or overt, as the person you're trying to convince might be suspicious. It looks like you don't want to cry in front of her and looks a bit embarrassed. You might even apologize for crying!
Warnings
- Do not make your face assume a strange position that causes you discomfort. Instead, relax the muscles in that area.
- Never look up at the sun to make your eyes water, as the sun emits enough radiation to ruin your vision for most of the day.
- If you have dark eye makeup, it will definitely be ruined and you will have to reapply it. However, if you spoil the mascara, this can enhance the effect.
- Don't irritate your eyes too much. You could hurt them if you're not careful.
- If you are using a stick or other type of substance to induce tears, it should not remain applied, as it could ruin your vision!
