Step-by-Step Instructions
1
Gather Your Liquids
Collect all the liquids and line them up. Color the water and rubbing alcohol with different food coloring.
2
Pour in Order
Slowly pour each liquid into the glass, starting with honey (densest) and ending with rubbing alcohol (least dense).
3
Observe the Layers
Watch as each liquid settles into its own distinct layer, creating a beautiful rainbow tower!
The Science Behind It
Liquids with greater density settle lower in the glass. Because each liquid has a different mass per volume, they separate into visible layers instead of fully mixing.
🤓 Fun Fact
Ocean water layers by temperature and salinity in a similar way, creating density-driven currents.
