Written by It’s freezing cold outside today, so we’ve been trying some indoor winter science activities. These crayon resist snowflake pictures have been a big hit, and they are very easy to create.
Crayon Resist Snowflake Art
You’ll need
White paper
Paint Brush
Water
Instructions
Draw a snowflake on the paper using the white crayon. You might need to press down hard. It can be a bit difficult to see what you’re drawing, but all will be revealed when you paint over the crayon.
Using the watercolour paint, gently paint over the crayon snowflakes. They should become visible as they are painted over.
The same technique works for leaving secret messages for friends or drawing other pictures.
Why do crayons resist water?
Crayons are made from wax, which repels water. They are hydrophobic. As you paint over the crayon, the paint slides off.
Washable crayons are not quite as good for this activity as wax crayons, but they work well enough to make a good picture.
