Make a DIY Diffuser // You’ll need: mineral oil, vodka, chopsticks, essential oil and a small vase. Mix ¼ cup of mineral oil with 2-3 tablespoons of vodka in your small vase. Once that’s mixed, add essential oil – you want your mixture to be 75% “base” and 25% essential oil. Then, insert your chopsticks. That’s it! Flip them once a day and enjoy the fresh scent of your choice.
