Arranging the frozen blocks of snow/ice and the spray painting were a big hit with the children last year. 

Instructions for ice blocks are:

1. fill a plastic container 3/4 full of water
2. add a few drops of food colouring
3. place in the freezer
4. remove the ice block, put the ice block outside and repeat.

Instructions for snow blocks are:

1. fill a plastic container with snow (I use the green grocery store containers)
2. add water and mix  (I mix in enough water so that the snow sticks together)
3. smooth the top of the snow block
   
4. let the container sit until frozen
5. remove the ice block and repeat.
6. cut the snow blocks into smaller sizes (I used a wood saw to cut the snow  blocks last year)
