Haunted Milk STEM Activity
Combining milk and food coloring looks so cool! It’s one of the most exciting STEM experiments for children to watch. With just a few tweaks or props, this is the perfect activity for Halloween. You can joke with your students that the milk is “haunted” for Halloween as it moves around like a ghost. Just make sure they know it’s a ‘friendly ghost”, so they don’t get scared.

With some everyday items combined with a couple of Halloween things, this low-prep Haunted Milk STEM activity will be the hit of the day!
- Cup of Milk
- Food Coloring
- Dish Soap
- Halloween Container-ghost, pumpkin, etc
- Pour enough milk to cover the bottom of your plate/container
- Carefully add drops of food coloring to the milk (Pro Teacher Tip: This is a great chance to talk about primary and secondary colors, and see who knows what two colors combined would make orange, purple, etc)
- Dip the toothpick into the dish soap so that it covers the full end (Q-Tips or a folded paper towel works well too)
- Touch the food coloring in different areas and watch it move across the plate- or “float like a ghost”, and see how the colors swirl together
- Watch the looks of awe and amazement on all your students’ faces!
