Gel Air Freshener

So far I'm 0 for 2 with making my own air freshener. Let's hope that I can redeem myself by trying a homemade gel air freshener.

Gel Air Freshener
You Will Need:
plain, unflavored gelatin or pectin
water for preparing gelatin
food coloring (optional, just for added flair)
essential oils
small glass jars or bowls  (I filled three with 2 cups of finished gelatin)
1 tablespoon salt (prevents mold)

Directions:
To make this, place 1-2 drops of food coloring in each of your glass jars or bowls, and then prepare the gelatin according to the package directions, adding the salt during boiling. Once the gelatin has dissolved in the water and it's ready to set, add 20-30 drops of essential oil and mix. Then pour into your individual containers and mix with the food coloring.  Check the strength of the smell at this time and add more oil if necessary.

I wanted to try three different scents so I grabbed Lavender essential oil, then I grabbed Eucalyptus and Citrus fragrance oils.  

 I followed the instructions and I put 20 drops of each oil into the glasses. The scent was pretty strong so I figured the 20 drops was plenty.  For some reason my gelatin rebelled and didn't want to set up when it was suppose to.  It took 24 hours before it finally turned into a gel.  I have no idea why.  It was just trying to annoy me I guess, it worked.

 Each glass was assigned a bathroom (each bathroom is roughly the same size) and I started the countdown to see how long the scent would last from each jar.

The Verdict: The citrus oil pooped out after 3 hours.  Even if my nose was in the glass I couldn't smell anything.  The lavender made it 9 days before it called it quits.  The eucalyptus made it a full 2 weeks.  Unfortunately, I don't know if it's the type of oil or the scent that made the eucalyptus out last the others.

By the time I took the eucalyptus out of the bathroom it was looking pretty depleted.  The gel was mostly evaporated (I didn't know gel did that) and it had left a green gooey funk around the edge of the glass.  It washed off very easily though. 

 Even though some of the scents didn't last long and if you try this you will have to experiment to find the right oil and scent to make it worth your while, I'm calling this a success, mostly because I don't want to be 0 for 3
