In this instructable, I will show you how to make a Portal 2 space core mask with a simple speaker which reads off space core quotes. This is simple instructable, and all the materials I needed for the project i found lying around the house, so i assume that you could likely find the materials rather easily. To make the mask, it takes a maybe 1 hour and 30 minutes (not including the time it takes for the paper mache to dry - which would be about a day), and all the experience you would need for making this mask would have already been acquired from preschool.
So with that said, off to the materials list.
Step 1: Materials
Here's what you'll need to make the mask:
-Newspaper and/or paper towel sheets
-Black and white paint
-A hot glue gun with glue gun sticks
-Cardboard tube (or tubes, depending on the size)
-Orange construction paper
-Dark somewhat see through sheet plastic (this is really the most difficult thing to find, but if you scrounge around you might get lucky)
The materials for the speaker which reads off space core quotes:
-An mp3 player of whatever variety
-A small speaker
-An mp3 of the space core quotes
