We've all seen patches of iridescent colours on a rainy day. Through another post on this site: What causes multiple colored patches on a wet road? I've also tried to understand the science behind it.
My question now is, if I'd like to create this in my house how should I go about this? From my understanding, we need a black background, some water, oil and light for this to happen.
[Q1] If this is the case, do oils like Olive oil work?
[Q2] Is the yellow light in homes sufficient to view this?
[Q3] Is there any way to fix this patch of colour? (To make the colours stay)
If the experiment goes well and if it is possible, I would love to photograph this phenomenon inside a studio!
Sharing some sample photos of the rainbow puddle below:
Edit: I was able to achieve the results on a wooden and glass base. Somehow a ceramic bowl (filled with water and a few drops of gasoline) just didn’t work. Thank you once again!!
