Step 14 With the Selection tool (V), select this new ellipse and the rest of the bell jar shape. Fill them both with the New Gradient Swatch 1 swatch in the Swatch palette.
Step 15 Using the Gradient tool (G), click and drag downwards from the centre of the semicircle at the top of the bell jar to create the correct shading for a 3D object.
Step 16 Now select just the ellipse at the bottom of the bell jar. Copy it and paste it on top (Cmd/Ctrl + F). Use the Eyedropper tool (I) to change its colour to that of the first extruded circle. Then shrink it slightly, holding down Alt + Shift to resize it from the centre. Set the opacity to 45% and group it with the rest of the bell jar. Set the opacity of this group to 65%.
Now place the bell jar above the base, with the bellows uppermost. Our work is done.
