Sun Printing at Brownies

We love the summertime sunshine, don’t you? The girls in the 24th Burnaby Mountain Brownies did a cool science-related craft using 100% natural sunlight at one of their meetings earlier this year.

The process is called Sun Printing. It uses special sun-sensitive (cyanotype) fabric to change colour. First, they laid out a design with various items items on the cyanotype cotton squares. They used a mix of natural materials like plants, and non-natural materials like foam craft shapes to make a design.

After leaving them outside for about 20 minutes, the items which had blocked the UV rays from causing a reaction on the cotton left a negative print.

The girls then rinsed the cotton squares in cold running water and then spritzed them with rubbing alcohol to quickly change the background to a lovely shade of blue. They then arranged the squares on pillowcases, carefully pinned them in place, and one of the leaders brought them home to sew them on.

The finished products show each girl’s unique design, made with a super awesome sun-powered printing process.

What a unique way to combine science and art in Girl Guides of Canada programming. This is just another example of what girls get up to at regular unit meetings.
