Put as much salt as you want into the plastic cup
Spray salt with the scent that you picked out. After about 5 sprays, sniff the salt and see if it is to what you want it to smell like, and keep doing this process, but shake after every 5 times.
Put in a squirt (about 8-10 drops) of the food coloring and shake for a few minutes
Put some on a paper towel and use it to be a pipeline type thing to get the salt into your glass jar. Do it a little bit by a little bit to be sure you have the correct amount.
Ta da! You made scented salt!
