I just found this on facebook, think I might make some up and try them out. Spring allergies are just around the corner.
DIY VICKS SHOWER PUCKS
1 Cup Baking soda
1/2 Cup Cornstarch
1/3 - 1/2 Cup Water
2 - 3 tsp Vicks vapor rub
Heat water enough to melt vicks in. Add in baking soda and cornstarch and mix into a thick paste, if you need to, add more water.
Line a muffin tin with paper cups, fill each cup about half way with mixture.
Let dry overnight. Remove from paper cups when discs are hard and store in an airtight container.
To use simply drop a puck in the bottom of your shower.
