EXPERIMENT: To observe how food dye travels through different beverages of varying consistencies.
RESEARCH: I did a trial experiment in class using different beverages to the ones used in this video. I also used diluted paint instead of dye, as I had no dye available. The results using paint were significantly different to the results in this video, as paint is obviously thicker and of a different consistency. I also noted the ingredients of each beverage to aid in my conclusions.
FINDINGS:
WATER: Dye travels down in ropes, forming pretty blooms. Blooms quickly dissipate and completely dye the water.
BEER: Dye travels down in ropes, then shoots back up from the bottom. I believe this is due to the bubbles in the beer.
COLA: I couldn’t see anything because the liquid was too dark. I should have used a lighter soda like lemonade, but I didn’t think of that. However, in my trial, the paint I used stayed at the top of the liquid and formed small ropes which stretched down about a centimetre. I think this has something to do with the sugar content and the carbonation of the drink.
ENERGY DRINK: Dye fell in thick clouds and quickly dissipated. In my trial, the paint shot down and rose up in a continuous cycle, similar to the beer. Again, I believe this to be because of the carbonation.
ORANGE JUICE: Dye stayed on top of the liquid and formed a layer about a centimetre thick. In my trial I used apple juice, which had a different effect, similar to the water. I believe the effect with the orange juice had to do with the thickness of the beverage, and possibly to do with the citrus.
MILK: Dye mostly stayed on top of the liquid, and streaked down a small amount.
Changes I would make:
I would probably use lighter-coloured liquids, and use a darker dye to start with (probably blue instead of red).
I really enjoyed this experiment and would be keen to elaborate on it 🙂
