Coke and Mentos Expieriment

We did the coke and mentos experiment at school.We had to write our own experiment about the how to do it. Making Lots of Bubbles After a lot of debate, scientists are now saying that the primary cause of Coke & Mentos geysers is a physical reaction, not a chemical reaction!Weird right. Their explanation is this process called nucleation. All the carbon dioxide in the soda is squeezed into the coke and looking for a way out. It’s going to go to any tiny bumps that it can get onto. Those tiny bumps are called nucleation sites places the gas can grab onto and start forming bubbles. Nucleation sites can be scratches on a glass, the ridges of your finger, or even specks of dust – anywhere that there is a high surface area in a very small volume. The surface of a Mentos is sprayed with a lot of microscopic layers of melted sugar. That makes it not only sweet but also covered with lots and lots of nucleation sites. In other words, ...

An open circuit is when the switch has not been push so there isn't a complete circuit there so energy can't go through. We use Tinkercad circuits.
