The goggles are designed to let in a smaller amount of light to help (NOT completely) prevent sun glare and snow blindness. They also help keep snow out of your eyes. This will probably take only a few minutes depending on how well you keep the duck tape straight while this is being made.
You will need:
Any piece of string (One that doesn't need to be used for anything else.)
paperclip (Only if you don't have string that can be given up)
