A black and white line drawing of two laboratory equipment. On the left side of the image, there is a conical flask with a long neck and a wide base. The flask has a narrow neck with a vertical opening at the top and a narrow opening at one end. The body of the flask is made up of a series of horizontal lines, which are used to measure the amount of liquid in a test tube. On top of the test tube, there are two small circles, one larger and one smaller, which appear to be floating in the air. The larger circle is slightly larger than the smaller one. The smaller circle is smaller than the larger one. Both objects are drawn in a simple, minimalist style.
