These were local rituals done to bring about a snow day. Especially when the informant was younger, there were lots of snowstorms in the area, and these rituals were said to help bring them. 

“The best days were always snow days because we had no school and everyone was free to do cool things like sled or make some money by shoveling snow. When we were young, like young, young, like 3rd or 4th grade we did all those things. We were flushing ice cubes, putting white crayons on the window sill… those other things. My mom actually found a white crayon on the windowsill of the basement the other day.” 

This ritual doesn’t have a designated time besides whenever a kid can’t take another day of school. It is a special kind of kid belief where flushing ice cubes creates snow or a white crayon will turn the ground outside white. It is also interesting because these rituals are only practiced in cold places, like the northeast of America.
