• Sift the bi-carb soda, citric acid, and corn flour into a bowl, mixing until no lumps are present.  Add soap coloring (optional), and then add water a few drops at a time.
• Use a spoon or your hands to combine the mixture, rubbing it between your fingers to evenly disperse the water.  You’ll know you’ve used enough when it sticks together/packs down and can keep its shape.

  It will still look kind of dry, but if you take a handful of the mixture and squeeze it, it should pack easily into a ball. Too much water will make the mixture continue to fizz and puff up more. 

  It may seem odd, but using your ears can help you with this step.  As you are mixing, bring your ear down to the bowl and listen.  Your mixture should be damp but not fizzing. If you used too much water in the mixture, it will continue to fizz and rise while it is drying. Constant and increasing fizzing means you may have added too much water, you can counteract this by adding more dry ingredients to the mix if it is too wet.
• Once you get the correct consistency, begin to fill your mold, pushing down the mixture into the holes and compacting it into place.  Compaction is an important step as it may mean the difference between hard and crumbly melts once they are dry.
• Set the melts aside to air dry for 24-36 hours (depending on the humidity where you live). When sufficiently hardened, your shower melts should release from your mold fairly easily, if they are still wet, they will not fall out with ease.
• While your shower melts are drying, create some labels for your samplers using your favorite word processing/publishing program. Be sure to include an ingredients list and directions for use.
• Print your labels on to printable sticker paper. Use a ruler and a craft knife to cut up your labels ready to stick on to your sampler packs.
• Once dry, release your shower melts from the mold. Place 4-6 shower melts into a cellophane bag with a 5ml bottle (or sample vials) of essential oil. Tie up/seal each bag and attach a label.

Directions for Use

• Add your essential oils to the shower melts right before using.  Drop the oils directly on top, then place in the corner of your shower where it will get wet, but is not directly below the water stream.  Watch it melt as you shower and wash any residue down the drain when you are finished.
