Pop Santa out of the chimney, warm up his cheeks, make colour changing decorations and give the gift of rainbows. With these cards your child has fun putting them together and exploring the science that makes them work, and then gets to share the science fun when they give them out to friends and family.

There are four designs available, each with their own scientific twist.  The cards come in kit form for your child to assemble and sign, and most card kits also come with some blank cards so that your child can create their own artwork if they want to.

Rainbow Christmas

All of our subscribers love our Rainbow Glasses! And we’re always hearing about how they want to share them with their families. So we’ve redesigned them to be a shareable gift on a Christmas card.

Save Santa

This is a pop-up card with a twist! Your little scientist will build a hydraulic rescue system using syringes and tubing to solve Santa’s annual chimney problem.

Don’t Have a Blue Christmas

The recipient of this card is tasked with giving Santa some rosy cheeks with a little chemistry. The cabbage juice-soaked paper will change colour when it reacts with an acid, such as lemon juice or vinegar. Your child will get some extra cabbage juice paper to play with, along with cream of tartar and sodium bicarbonate that they can use to make a chemical painting. It’s pHun!

Merry and Bright

Christmas card changes colour in light

The brighter it is, the merrier this card becomes. It’s covered with photochromic decorations that change colour under sunlight (‘photo’ means light and ‘chromic’ means colour). Your child can use our template or create their own decorations from a sheet of photochromic material.
