. Ice cream bucket/round container (for making the giant marshmallow shapes)
. Snow shovel (for mounding snow together to make scooping into the bucket easier)
. Water spray bottle (for spraying the walls)
. Large bucket of water, probably best kept in the garage (for refilling the spray bottle)
. Two to four boards, each board 1 inch x 8 inches and each 3 to 4 feet long
(These boards are optional for those who would like to have doorways with a lintel or "roof" over each.
We outfitted only two of our doorways with lintels because we had only two boards.)
. About 25 "manhours" (three boys worked after school on Friday and again on Saturday)
Step 1: Making Marshmallow Building Blocks
Start making snow "marshmallows." As demonstrated in the pictures shown above, pack snow into ice cream bucket. Be sure to press snow in well, packing down with your fists, then refilling and packing again until you have achieved a dense marshmallow. Dense marshmallows hold together and make better building blocks.
After you have packed the bucket well, wipe the top until level. Invert the bucket and release the marshmallow (you may have to shake the bucket a bit to cause the marshmallow block to release). Voila! You have a marshmallow building block. If the marshmallow block does not release from the bucket, either your snow is too wet or you have packed a bit too tightly.
