Make Your Own Color & Smell Combinations With These Easy Air Freshener Recipes

2 cups water
4 packages Gelatin (plain)
15 to 20 drops Essential Oil (adjust to personal preference)
1 to 2 TBS salt
Food Coloring

Directions:

• In a small pot, mix 1 cup water, essential oil and food coloring. As soon as it starts to boil, remove from heat.
• Completely dissolve gelatin and salt in the hot water then add the other cup of water (cold)–stir well (gently so it doesn’t foam).
• Pour into jars and set aside for a couple days before using so the gelatin has a chance to completely set (you can refrigerate to speed up the process). Once cooled, cover with lids that have a few holes punched in them to allow fragrance to escape.

The salt in this recipe is used to help combat mold, please make sure to add it.

Alternate Recipe:

• Follow the recipe above but substitute the 2 cups of water and the essential oil with 2 cups of concentrated liquid potpourri. As above, heat 1 cup first with the food coloring, remove from heat, dissolve the gelatin and salt then add the other cup.

Super Smelly Jelly

• 3/4 cup boiling water
• 1 pkg of 4-serving jelly powder (ie. box of instant Jello)
• 1 Tbsp. vodka
• 1/4 tsp dish soap
• Essential Oil or Fragrance

Combine & set in a jar with holes poked in the top. The vodka is to help prevent the jelly become moldy.

Optional:

• Add embellishments (embedded items) similar to the gel candles ^[2] embedded items ideas (listed at the bottom of the page).
• You can layer the colors, simply allow one color to set completely for a few days before pouring the next layer of color.

Jars

• Make sure the jars are completely clean before pouring in the hot liquid.
• You could cover the top with lace or netting instead of jar lids. Tie decoratively with ribbons, raffia, whatever you fancy.
• Any heat proof glass jar will do. Collect jam & jelly jars, mason jars or even baby food jars can be used for the Smelly Jellies.
