Fun of stacking layers of color liquids
You will need:
- Water (10cc)
- Salad oil (10cc)
- Rice wine (10cc)
- Dish washing liquid (10cc)
- Syrup (10cc)
- Bamboo chopsticks
- Test tube (one piece)
- Food colors or coloring materials
✽You can perform this experiment with a minimum of three color liquids.
- Apply different coloring materials to make different color liquids.
- Next, pour different liquids into the test tube.
- Carefully observe the positions at which these color liquids come to rest.
How it works:
Different liquids have different structures. Some structures are tight and solid, while others are loose. Different liquid structures cause liquids to have different densities and weights. Liquids with a heavier density (such as dish washing liquids and syrup) settle in the bottom layers and liquids with a lower density settle in the upper layers. The lighter liquid will naturally “float” in the upper layers and that is how the fun of stacking liquids comes about!
