Soda geyser

The eruption is caused by a physical reaction, rather than any chemical reaction. 
The conversion of dissolved carbon dioxide to gaseous carbon dioxide forms rapidly expanding gas bubbles in the soda, which pushes the coke contents out of the bottle.

The human body is electrically conductive!!!!

A piece of fruit or vegetable can  also conduct electricity, as basically anything else that’s organic. We have  created a fun  project: a digital fruit piano.
What sound does a banana make??????

How much sugar is there in a can of soda? (Density)

If you put a can of regular coke or pepsi into a container with water, it will sink. While, if you put a can of diet coke into the same container, it will float.
 Coke has more mass because of the 35 grams of sugar it contains, compared to the 125 milligrams of sweetener in a can of diet coke.
The cans of soda have exactly the same volume, or size. But their density is different  due to what is dissolved in the soda. If you look at the nutrition facts on a can of regular soda, you will notice that it contains sugar...a lot of sugar.
Rethink your drink!!!!!
