These gel air fresheners are perfect. This project takes a total of five minutes to make, is highly economical, and each jar should last you about a month. This would also make great gifts!
Into make these little beauties, you first need a heat-proof jars, food colouring colours of your choice, and essential oil. You can find inexpensive essential oils of various scents at craft stores and some grocery stores. I chose a raspberry scented oil...it smells delightful!
Into each jar, drop a few drops (I repeat...a few...it doesn't take more than 2 or 3) of food colouring.
Then, put in about 30 drops of essential oil, give or take. The more essential oil you put in, the stronger the smell.
Now for the fun part. Gather up 4 envelopes of unflavoured gelatine, a tablespoon of salt, and 2 cups of cold water.
Why salt? Salt (or vodka) apparently help to keep the gel from moulding. Interesting fact, isn't it?!?
Get one cup of water boiling on the stove. When it begins to boil, whisk in the gelatine, stirring until it's all dissolved.
Then, pour in the other cup of cold water and the salt, stirring until the salt is dissolved.
Quickly pour the hot gelatine mixture in each of your jars, and then use a disposable stick or spoon to stir it into the oil and food colouring.
Let these gel overnight, and then voila! Air freshener!
