We found that mixing the oil and food colouring before pouring it in was too complicated, especially since he’d have to demonstrate it in class himself. So what we did was we put water and then the oil (oil by it self doesn’t need too careful pouring). And then, we dropped in food colouring drops on top of the oil. we managed to put all the different coloured drops before they sank to the water and the ‘fireworks’ began. So it was cool.

We also did one round with cold water (not intentionally, lol). We observed that it took longer for the coloured drops to fall into the water, and even then, it slowed the effect of fireworks. We didn’t like it all that much. Also, we were intrigued to see that some colours dropped faster than others. Yellow was stubborn, blue was faster. My theory was that yellow had the least composition of water vs dye compared to blue (97.3% vs 98.7% in the colouring we were using), so was less dense and so took a longer time. This is just a theory. 🙂

But all in all, while we had fun watching the fireworks, I thought this had little educational value (other than water is more dense than oil). .. hmm.
