Chemistry Jokes and Puns With Explanations. What Are Examples of Hydrogen Bonding? The food colouring actually sinks through the oil into the water layer as water is more dense than oil. This is the basis for a firework in a glass experiment.
The two can be forced to mix by adding an emulsifier which creates a mixture of water with oil molecules spread evenly through it or vice versa. Use water and oil to demonstrate density. You can make a very simple density jar with just oil and water or use other liquids to make a more complex density column. Find out what happens if you put a gingerbread man in oil and water. Try to clean up an oil spill! Interesting information, but only part of a water molecule is positively charged the part around the oxygen atom.
This was very insightful. I plan on doing this for my upcoming Science Fair. I like how this is explained. Simple enough for kids to understand and complex enough to get people interested in science.
Well done! This is very nice and easy to do. I am doing this for the Science Fair.
