Water Experiments

1. The Starting Point
I started this project by researching and focusing on the change of state from water to ice. I came across a very interesting campaign, which I liked a lot, called the ‘Melting Men’ campaign. What they were trying to do was to raise awareness in people on the global warming crisis. Miniature human ice figures slowly melted away in the mid day sun, in other words, ice melted to water! So this
definitely had something to do with the project.
2. Getting Started…
I started by playing with a very simple idea: photographing ice melt. I took shots at regular intervals and combined them into a simple stop-motion to see the process of ice melting.
3. Exploring an Idea
Since I was really interested in the global warming issues, I tried to play with that concept, and to create something that will raise awareness in people. Unfortunately, I don’t think the method I used really worked :(
4. Trying out many ideas
I looked at different water experiments done by other people on youtube for inspiration. I was very fascinated by some one them and so I wanted to try them out for myself, but of course I made sure that I chose the ones I could easily do myself at home.
The SUPERCOOLING experiment
The first one I tried was the ‘supercooling’ experiment. The idea was to freeze coca cola in 2 seconds. The way to do this was to put a (glass) bottle of coke in the freezer for 3-5 hours, depending on your freezer. When it’s time, you take out the bottle, carefully open the lid, then you knock another bottle against the opening of the first bottle. (This is the fun part) You then watch the coke inside instantly freeze from top to bottom.
But when I tried it out, it didn’t quite work out like in the video. I think it was because I accidently shook the bottle when I opened the lid, so the coke inside became fizzy, instead of freezing.
The LAVA LAMP experiment
The second experiment I tried was the ‘Lava Lamp’ experiment. I really liked this one. It was quite easy to prepare, and didn’t take a long time to do. First you pour water into a clear bottle, then add your desired food colouring. In my case I added pink, because it is quite bright and visible. The you fill the bottle with cooking oil. The final part is the highlight of the experiment. You take a tablet of calcium (the normal ones you find in drugstores) and drop it into the bottle. Within second it will start to bubble, and a lava lamp-like effect will occur. This works because water is denser than oil; when the gas pushed it up, it will fall through the oil back down to the bottom of the bottle.
The first few times I tried it, the contents of the bottle fizzed up too much that I couldn’t see the coloured blobs rise and sink. I think it was because the bottle I used was too small. The next time I only used half of the calcium tablet, and found that it worked much better, because it fizzed up less and you could see the coloured blobs clearly in the bottle. As a conclusion, I think this experiment was a success! :)
