- White rag (or old white T-shirt)
- Black Permanent Marker
- Milk Jug
- Use scissors to cut out a hole out of the top of the rag.
- Lay the rag flat down and use the black permanent marker to draw a face on it.
- Place the rag over the milk with the lip in the middle of the hole you previously cut out.
- If you like, you can trim the bottom of the rag around the milk to give it a better fit.
- Enjoy your ghost milk!
