If you use pure, therapeutic grade essential oils don’t throw the bottles out when they’re empty.
For this diy, I like to use spearmint, lemon, thieves and cinnamon to make my flavored toothpicks.
They’re great if you’re planning on having company over, you can leave out some flavored toothpicks out for your guests. I personally use these a lot in my coffee 
When you think your bottle of essential oil is gone, open it up and look in the bottom! There’s still some left and it’s the perfect amount to make flavored toothpicks
