Rainbow Density Tower
Learn about density by creating a colorful tower of liquids that don't mix!

Have you ever wondered why oil floats on water? Get ready to create an amazing Rainbow Density Tower that looks like liquid magic! This colorful experiment teaches you about density - how heavy or light different liquids are compared to each other. It's like building a skyscraper, but with liquids that stack themselves!
When liquids have different densities, they separate into layers just like how a heavy rock sinks in water while a light feather floats. The heaviest liquid becomes the bottom floor of your tower, and the lightest liquid becomes the top floor. Each liquid finds its perfect spot based on how dense it is!
Parent Supervision Note: This experiment requires adult oversight throughout all steps. Please supervise the pouring process and ensure children work carefully with potentially sticky materials.
EXPERIMENT STEPS
What You'll Need:
- Clear tall container (mason jar or tall plastic cup)
- Honey (1/4 cup)
- Light corn syrup (1/4 cup)
- Liquid dish soap, any color (1/4 cup)
- Water with food coloring (1/4 cup)
- Vegetable oil (1/4 cup)
- Large spoon for pouring
Step-by-Step Instructions:
- Pour the honey slowly into the bottom of your container - this is your heaviest layer
- Add corn syrup by pouring it very slowly over the back of your spoon so it doesn't mix with honey
- Pour the dish soap the same slow way over your spoon - watch it find its layer!
- Add colored water drop by drop over the spoon back - be extra patient here
- Finally add oil as your top layer - pour slowly and watch your rainbow appear!
- Wait 2-3 minutes for all layers to settle perfectly
Your Rainbow Density Tower shows how the natural world organizes itself, just like how layers form in the ocean or atmosphere!
