 Ingredients – Guar Gum Gel Version (Skin-Safe, Natural)

Makes about 1 cup of Grinch Gunk

• 1 cup warm distilled water 
• 1 tsp guar gum powder (natural thickener) 
• 1 tbsp glycerin or aloe vera gel (skin soothing + slip) 
• 5–10 drops peppermint essential oil (or vanilla-mint blend) 
• Green mica powder or food-safe soap colorant 
• 1 tsp baking soda (optional, helps soothe skin) 
• Small jar or squishy tub container 

Optional:

• A pinch of eco-safe glitter 
• Mini plastic Grinch or Elf toy 
• Printable “Help! The Grinch Got Me!” tag 

 Melt-and-Pour Version (For Squishy Soap-Like Texture)

• ½ cup clear melt-and-pour soap base, chopped 
• 1 tbsp vegetable glycerin 
• Green soap colorant or mica 
• 5 drops peppermint essential oil 
• Heat-safe jar or silicone mold 

 How to Make – Guar Gum Version

1. In a mixing bowl, combine warm water and glycerin. 
2. Slowly sprinkle in the guar gum powder, whisking constantly to prevent lumps. Let sit for 5 minutes to thicken. 
3. Add baking soda, essential oils, and green mica. Whisk again until smooth and gooey. 
4. Add glitter or shimmer if using. Pour into small jars. 
5. Let sit uncovered for 10–15 minutes before sealing. 

 How to Make – Melt & Pour Version

1. Gently melt soap base in microwave or double boiler until fully liquid. 
2. Stir in glycerin, mica, and essential oils. 
3. Pour into jar or mold and allow to cool and firm up. The result: a jiggly, jello-like slab of bath slime! 

 How to Use Grinch Bath Slime

• Scoop a tablespoon or two into the tub as the water runs 
• Rub between hands for silly slime play before rinsing 
• Watch it dissolve into a silky, minty soak 
• Store leftovers sealed, out of sunlight, for 1–2 weeks (guar gum version) 

Note: As with all kids’ bath products, adult supervision is recommended. Avoid eyes and mouth.
