Walking along the Mobius band allows to reach both sides of the Klein bottle.

Open a separate display, which can be enlarged to fill the whole screen, using

• Right-mouse click, select "New Display"

If interaction with a larger display is too slow then disable the transparency of the Klein bottle half using

• Right-mouse click, select control panel
• Menu INSPECTOR->DISPLAY
• Activate the Klein bottle by selecting it in the left column.
• Menu INSPECTOR->MATERIAL
• Disable the checkbox Transparency.

Instead of using the display inspector to select a surface, one can use a shortcut: keep the control key <Ctrl> pressed and left-click on the desired surface in the display.
