Test Tube Design.
Step 1:
Let’s start out by creating a new file. I used a 300×300 pixels canvas set at 72dpi, and a white background. Now make a new layer set and name it 'Tube Design'.
Select the Rounded Rectangle Tool and set the radius setting to 40 px. In a new layer draw a small cadet blue rounded rectangle with #8EBFE0 color shade and 17 x 94 px dimensions. Then cut the top rounded corners of the rounded rectangle as shown below.
Step 2:
Under Layer Style(Layer > Layer Style) add an Inner Shadow, Inner Glow and Gradient Overlay blending options to the cut out cadet blue rounded rectangle layer. Then set the layer's opacity level to 51%.
