Vacuum Pump: This element pumps gas out of the container during Run mode. You must attach the vacuum pump to the blue hotspot on the lower right side of the container (see Container (Ideal Gas)).

To turn the vacuum pump on or off, click on the switch as indicated in the figure to the right. The switch is blue when the vacuum pump is off and red when the vacuum pump is on.

You can delete the vacuum pump, but you cannot move it.
