Making your own gel air freshener for the car is a fun, easy and money-saving project. While most gel air fresheners have a very strong, artificial scent, you customize your homemade gel air freshener to the exact color and scent you want. You can even color your gel air freshener. The easiest way to prepare a gel air freshener to ride in your car is to pour it into a petri dish and allow it to settle. You can find petri dishes or similar items in any craft store.
Boil one cup of distilled water in a large pot.

Pour 4 packages of unflavored gelatin into the boiling water, and stir until dissolved.
Remove the pot from the heat and and add a cup of room-temperature distilled water.
Add as much essential oil as you like. Usually 10 to 20 drops is enough.
Add a few drops of food coloring to color the gel.
Add 1 tsp. salt into the gelatin mixture. This will inhibit mold growth.
Pour the gelatin mixture into the petri dish.
Allow to set at room temperature for 24 hours, or until it is firm.
Cut one piece of clear packing tape and loop it over itself, so it forms a continuous sticky loop. Stick it onto the back of the petri dish, and then affix the petri dish onto your dashboard.
