As part of our big question of ‘Fire; Friend or Foe?’ We have been investigating the best materials to use for fire fighters outfits.
We learned about Charles Macintosh who used wax to prevent water from getting into the fabric. We decided to see if this was true by creating a wax relief painting. We used crayons, which are made from wax, to draw fire shapes and washed it with orange paint.
We were amazed to see that the wax was water resistant. As the paint just wouldn’t stay on that waxy parts. The non waxed parts absorbed the wet paint.
We found that the thicker and harder we pressed with the crayon, the more water resistant it was.
