Marbling with crayons!

This is a really fun craft project to try with children.  We marbled eggs and paper but you could marble many things using this technique.

It doesn't involve chemicals with toxic fumes, but it does involve boiling water so care needs to be taken but I love the effect that it achieves. 

 
 
For this project, you will need...
  • Crayons of different colours - NOT CHEAP ONES: they don't work
  • A pot
  • Boiling water
  • A pair of tweezers
  • A grater
 
How to get the marbling effect...
 
STEP ONE
 
Grate a small amount of each of the colours you want to use, we prepared six colours - I would say about a dessert spoon size of each.

 
STEP TWO

Fill your pot with boiling hot water.  We boiled the kettle.

STEP THREE
 
Sprinkle your grated crayons over the water.  You should notice it melts immediately.

 
SCIENCE: you could talk about how a solid has become a liquid and the reason why - heat.  Also talk about why the grated bit of crayon are floating - you could put a whole crayon in a sink full of cold water and guess whether it float or not.
 
Check out these experiments:
 
 
 
STEP FOUR

Get your egg or card or paper that you want to marble, pick it up with tweezers for safety reasons - then dip your object in the water and then slowly pull it back out.



You should have a lovely marbled effect now.  Experiment with different colours...


 Eggs work well too...
