Some with colored water and some with just water
Got inspiration on this page to freeze rubber gloves. Four little ones aged 1 1/2 and 2 1/2 filled the gloves with feathers and I had in water.
Some with colored water and some with just water. We hung the gloves in a tree out in the garden (I work with 4 little ones in my own home). When we had a week with temperatures down to -13 degrees, the color in the gloves had in a way contracted. Today it looked like the gloves had veins.
