Mix water with baking soda and glitter to form a thick paste.
Press the mixture into cookie cutters to shape a snowman.
Use a paper towel to remove excess liquid and clean the edges before removing the cutters.
Decorate the snowman with icing, sticks, and a small carrot nose.
Let children interact with the glittery snowman before adding vinegar to make it fizz.
Encourage them to touch and squish it as it fizzes.
