1. Merge through vibration
My basic material is oil. Based on some common senses and internet information, there are key properties of oil: oil & water do not mix; oil is lighter than water; transparency change during process of freezing; flexible and lubricant; vibrate along sound frequency (this property shared with water)

3. First Ideas and Main Concept
Water droplets keep individual in oil, because oil is a hydrophobic material. Due to high surface tension of water, water droplets shrink to sphere shape to keep the minimum surface.

The merging process due to vibration.
Initially, i found the fact that water droplets could stay individual quite interesting. Thinking further, I would like to investigate some factors preventing them merge or making them merge.
4. Modelling and Fabrication process

I went on further experiment to see how structures and sounds impact on water droplets merging in oil environment.

5. Final Outcome
From the experiments, I realise that certain structures could diverse the pressure more efficient that without a structure.

As sound indication, water droplets in oil could also be used in the situation of visualising sound presence.
