How do you Work a Thermos?

Okay so you have the ghost ready to be captured, it's your first time using your thermos so you fly over to your best friend and he hands you your handy dandy Thermos. You aim the Thermos at the ghost and… now you are stumped… you have not a clue how to use a Thermos.

When using a Thermos it is simple! You do not twist the cap off and you do not flip it off, you pull it off. Next you aim it at the ghost and press the button that activates it. Next the ghost should get sucked into it. When the ghost is in the thermos all the way put the cap back on as soon as you can.
