How to Draw a Lab Flask in 8 Easy Steps (for Kids)

Easy steps in drawing a lab flask.

A flask is a type of container made of glass. They are a common piece of apparatus used in laboratories.  The amount of volume they can store, which is expressed in metric units like liters (L) or milliliters, determines the size of the object (mL).

Depending on what they are used for, their design varies, but typically they have a broader body that houses the materials and a relatively narrow neck with a top aperture. The entrance point for materials into the body is the aperture. Some flasks have top openings and many necks. This container is used to contain substances.

Let’s now draw one of the apparatus used for the experiment. By simply following the 8-step tutorials below.

Simple steps in drawing a lab flask.


  • Pencil
  • Paper
  • Coloring material


Step 1: Draw the Body

First step in drawing a lab flask.

Lab Flask has many types of shapes but in this tutorial, we will be making a round lab flask. To do this, just simply draw a big circle in the middle of your paper. If you have a hard time drawing it, you can find an object and then trace it to make a perfect circle. 

Step 2: Add the Neck Part

Drawing rectangle and circle for lab flask.

Let’s make this simpler by drawing a long vertical rectangle on the upper, and center part of the body. The size of the rectangle is all up to you. If you want to make longer then make it longer. If you want a shorter one, then make it shorter. Just make sure that the rectangle will overlap the upper portion of the body.

Step 3: Draw the Mouth

Third step in drawing a lab flask.

This time, we will draw the mouth of the lab flask. To be easier just draw a small horizontal rectangle on the upper portion of the neck. Make sure that this will slightly go beyond on both sides of the neck’s lab flask.

Step 4: Add Details

Fourth step in drawing a lab flask.

Lab flask mouth will always be round, now let’s make the mouth round by adding a curve line on the four edges of the rectangle. Draw the curved line inside the rectangle. See the reference image above for you to be guided.  

Step 5: Remove Extra Line

Removing extra details in drawing a lab flask.

Now, that you added a round edge of the mouth let’s erase the edges from the rectangle that you made earlier. I want you to carefully erase the edges. Make sure not to include the important part of the lab flask.

Step 6: Add the Eye Guide and Remove Extra Lines

Drawing Eye Guide for a lab flask.

To make your lab flask cuter, let’s add eyes to it. Draw two circles in the middle of the body of the lab flask. This will serve as the eye guide for your lab flask. Then remove all the lines inside the mouth of the lab flask.  

Step 7: Draw the Eyeballs and the Mouth

Drawing Eyeballs and the Mouth for a lab flask.

The next thing that you need to do is to draw the eyeballs inside each eye guide. We do this by drawing a shaded crescent moon shape inside it. Then draw an inverted letter under the eyes. This will serve as the mouth of the lab flask. Then draw a short horizontal line in the neck part to clearly see the chemical inside it.

Step 8: Finish up!

Final step in drawing a cute lab flask.

To finish your drawing, let’s add color to it. Lab flasks are always transparent to see the chemical inside. Also, it is made up of glass or plastic but the chemicals inside have different colors depending on your experiment. This step will be all up to you. Enjoy and congratulations Kiddo!
