Use Jello as a lipstain! Pour the powder mix into a bowl and moisten a Q-Tip with water. Then, being very careful not to use your fingers since the red stains stay put, dip the Q-Tip into the powder and apply it directly to your lips.
This has to be one of the more stranger pins I've found on pinterest. It's not that it wouldn't work, but it more or less confuses me. The dye in jello is the same used in food coloring. It would probably be easier to carry a small bottle of red food coloring and dab that onto your lips instead of carrying around a packet of powdered jello. If you're looking for a more natural route, you could probably keep a slice of raw red beet in a zip top bag and use that instead.
So what do you think? Anyone wanting to trade in their favorite lipstick for a packet of jello?
