The Cumberland High School interactive Science Club student’s presentation features water testing, and water decomposition also known as Elephants Tooth paste, unsure about this experiment visit youtube. The students also set steel wool on fire and make Super giant bubbles that can engulf a man, all because water molecules are able to stick together.
Year 11 students Julian, Josh, Gabbie, Chris and Ben regularly demonstrate how water can become acidic similar acidity to that of a soft drink by using dry ice. The gas dry ice produces is actually tiny droplets of water.
Emma and Rebecca make Elephant’s tooth paste- so called because it looks like toothpaste coming out of a tube. Here water is produced as a by product of an experiment that is fast and furious and hot.
A fiery sphere, most people don't consider steel flammable but steel wool will burn vigorously if you give it enough oxygen. The result is surprisingly entertaining because tiny bits of material melt, creating a fireworks like pyrotechnic display. Scott, Thomas, Alexis, Maryanne and Anika demonstrate.
Now the biggest splash of all the Super bubble. So you want to become a “bubbleologist” follow the recipe below and make your own giant bubbles. Water has surface tension this allows water and detergent to form bubbles. The surface tension is strong however to keep bubbles from breaking we increase the surface tension of the water by adding glycerine which allows the great stretching phenomena.
Super Bubble Solution
What you will need:
- 2 cup dishwashing detergent (Morning Fresh detergent works best)
- 9 litres (1 bucket) of just warm Water
- 2 tablespoon Glycerine
Happy water gymnastics.
