First, you need to harvest some snow. The NWS predicted rain Friday night turning overnight to snow.
IKEA Torkis baskets outside to harvest some snow. I put them on a bench, so they would equilibrate to the air temperature instead of the ground temperature.
Back inside, I put the scrunched up the damp clothing in plastic bins, mixed some Procion fiber-reactive dyes with water, and splashed the dye in.
For the snow dye experiment, I decided to supplement with ice from the ice-maker in the kitchen. (Isn't it ironic that we run ice-makers in the winter?)
I sprinkled one teaspoon each of midnight blue and strong navy Procion dye powder on the slush/ice/shirt tostada.
In Boulder, I use a Nina Soft Spin Dryer, which is a centrifuge for fabric/clothing.
