1. Cut a piece of duct tape about 30cm long
2. Fold it in half (with the sticky side on the inside)
3. Cut two slits (not holes) for the eyes and a triangle for the nose. The slits shouldn’t let in too much light but should allow you to see what’s in front of you
4. Make a headband by cutting a hole close to both ends of the tape and threading a rolled up length of tape through each hole so it fits snugly around your head. You could also use a piece of string or a bootlace for this.

5. Use a small patch of tape to secure the headband to the goggles.
