Double Rainbow Greeting Card

It's getting a little late for Christmas, but that's okay, cards work for Valentine's Day too. Here's a full-on double rainbow pop-up card for someone special in your life.

P.S. If anyone out there doesn't get the joke, a quick YouTube search on 'Double Rainbow' should explain it.

Step 1: Materials

It's easy to make a double rainbow pop-up card. All you need is:

My handy double rainbow graphic (below as a Word document), or make your own
A rectangular piece of very light cardboard the same width as the big rainbow (6 5/8", 168mm for me, yours may differ)
Glue
Craft knife
Ruler
A greeting card, or you can make your own

Nice project, and a good, simple example of how to make pop-up art.

Just a minor physics complaint :-) Because of the extra internal reflections, a true double rainbow has the colors reversed in the outer (dimmer, secondary) bow. In your drawing, the outer one should have red on the inside, and violet on the outside.

Also, in nature, there's a region of darkness between the two, but I think putting grey on your pop-up would not look as good.

And there I was, naively thinking I was publishing the one Instructable no physicist would take issue with... dammit.
