Water, Oil & Food Colouring

15

Water, oil and food colouring do not mix together

Water droplets with food colouring Food colouring droplets

slide-16
SLIDE 16

Water, Oil & Food Colouring

  • Dropped food colouring through oil
  • No stained oil
  • Dropped water with food colouring through oil
  • No stained oil
  • Drops merged over time
  • Conclusion: Food colouring is not oil soluble

Speed of Water through Baby Oil

  • Dropped coloured water through baby oil
  • Varying heights
  • Speed of water through baby oil is roughly

3.1 cm/s

SLIDE 21

Problems of old prototype

  • 1. Aesthetically displeasing
  • 2. Water leaked often from the jar
  • 3. Low display quality

slide-23
SLIDE 23

Improving... Water leaked often from the jar

  • Better sealage
  • Replaced containers

23

slide-24
SLIDE 24

Improving... Low display quality

  • Oil instead of air
  • Slows water down
