Hi, my name is Josh D I live in Australia, Victoria, I go to school at B.L.P.S and I am in grade 4. I am also in our extension program L.E.E.P and I am part of the Junior School Council. Here is my page.

Experiment 1:

The below was originally published May 10, 2012 at http://blpsjoshd.global2.vic.edu.au/2012/05/10/why-does-diet-coke-and-mint-mentos-react/ Why Do Diet Coke And Mentos React? I researched this question and here is the answer: The mentos have many small, microscopic holes. These quicken the release of CO2 (carbon dioxide) from the coke. The carbon dioxide (along with the coke) is spurted out the top, as it is quickest way out of the bottle. The different chemicals in both the mentos and coke make foam and that too is spurted out the top of the bottle. So that is why you get an eruption when you combine mint mentos and coke. I found this image on the following page:



Experiment 2 The below was originally published May 16, 2012 at [] Materials: 1 clear glass, 1 clear large bowl full of water and 1 scrunched up piece of paper.

Procedure: 1. Stuff scrunched paper into the glass so it will not fall out. 2. Plunge glass into bowl. 3. Lift out glass from bowl. Result: the paper is dry! How this works: The glass is filled with air, when you plunge the glass into the bowl the water can only get into the cup by squeezing (or compressing) the air. Air can be compressed a little but eventually the air must push back and force the water out which blocks the water from reaching the paper. The air pushed the water away from the paper and kept it dry.
