If you are having troubles figuring out here to cut the slit, use a ruler and a pencil to draw an X across the circle. Cut along one of the X's arms towards the middle. Overlap the two edges of the slit until the circle turns into a cone. It needs to be big enough to sit on top of the tube without falling through. Tape or glue the cone together. A glue stick or double-sided tape will work the best here. Don't use hot glue; it is too bulky for this step. Draw a ring of hot glue along the rim of the paper towel tube. Place the cone on top and press it into the glue. Work quickly; hot glue sets up fast. You can use regular tacky glue, but you'll have to wait for it to dry. Make sure that you are gluing the cone to the end that does not have the slits.

Use the bathroom before you start the movie, and have your snacks and drinks handy as well. Click on your movie party conversation or group and hit the camera button, or the phone button if you're just doing an audio call. You may need to give everyone a few minutes to get situated before they will be ready to watch a movie. Decide beforehand if you'll be doing a video or audio call. You can start from the title screen, or you can pause at a frame and show everyone the screen to match it. This makes it easier to sync your movies if some people have different means of watching the film, such as streaming content providers. This is the tricky part. Have one person count for everyone, then hit the play button at the same time. With a little effort of fast-forwarding and pausing the movies, you can adjust the movie so you don't get an annoying echo over Skype.

You can also have everyone's Skype muted, and use the chat feature to talk to each other without interrupting the audio.
