In a large bowl, combine Epsom Salts, baking soda, and citric acid. Stir to combine.

Add in Eucalyptus along with dried flowers and food coloring if desired. Stir to combine.

Spray your mixture with water and stir until it is the consistency of damp sand.

Squeeze a bit of your mixture together to make sure it holds its shape lightly. If needed, add more water.

Spoon mixture into your mold. Let the bath bombs dry for 24 - 48 hours.

Bath — Fill your tub with warm water. Add 1 bath bomb to the water. The Eucalyptus will bring a cooling and soothing sensation to your body while opening and clearing your airways.

Shower — You can use these in the shower as well. Simply put the bath bomb just outside the stream of your shower so that it slowly dissolves with water.
