You might know that sunlight is made up of rainbow colours, but have you ever wondered what the world would look like if we randomly removed one colour? Let's make a pair of rainbow vision spectacles! Through these glasses, you'll see colour and light changes that are normally invisible, exploring the magic of light!
Download and print two copies of the template. Cut along the black edges using scissors, making sure to cut out the grey circles as well.
Take white card and cut two 21cm x 7cm rectangles.
Using a pencil and ruler, draw guide lines on the cut rectangles as shown.
Fold the grey circles from step 1 in half, align the fold with the horizontal line and marked points, and draw a circle with your pencil. Repeat for the other side.
Take the marked rectangles and fold the corners inward along the centre horizontal line.
Cut out the circles drawn on the card. Then cut away the folded corners along the crease lines. Repeat for the second rectangle.
Cut two 4cm x 4cm squares from each of the 6 different coloured cellophane papers and trim the corners as shown.
Apply double-sided tape to the templates and stick the coloured cellophane over the cut-out spaces. Do this for both templates.
Ensure the cellophane-covered side faces up. Apply double-sided tape to the remaining templates and align them with the prepared ones, creating your spectacle wheels.
Use a pencil to make holes in the centre black dots of both assembled wheels.
Align the wheel lenses with the circular cut-outs in the rectangular cards. Pierce through the wheel centres with a pencil to mark holes in the rectangular cards. Repeat for both sides.
Assemble the glasses in this order: rectangular card-wheel-rectangular card. Secure with split pins through the holes made in step 10. Repeat for the other side.
Cut two 30cm x 4cm strips of card and fold them 2cm from the right end as shown.
Attach the folded strips to the glasses using double-sided tape.
Have someone help measure the glasses around your head, marking the correct position. Ensure the glasses sit properly in front of your eyes.
Cut a 2cm slit from bottom to top on the left strip at the marked point, and from top to bottom on the right strip. Slot them together as shown to complete your rainbow vision spectacles.
Put on your glasses and rotate the wheels to experience different colour worlds!
The sunlight (white light) we see daily is actually composed of seven colours: red, orange, yellow, green, blue, indigo, and violet, together called the visible spectrum. When white light passes through water droplets or other objects, it refracts and separates into different colours, like a rainbow. By wearing rainbow vision spectacles, your eyes filter out certain colours, allowing you to see different light and colour changes.
