Dancing Raisins

Raisins aren’t appealing, tasty snacks since they are shriveled and dry but it can change with a can of Sprite into scientific terms that we don’t use often. The demonstration I chose to do is called “Dancing Raisins.” It is a very simple demonstration that only requires a cup of clear carbonated soda and a box of raisins. The purpose of “Dancing Raisins” is to demonstrate how carbon dioxide bubbels cause a change in an object’s density and buoyancy. The materials that I used are a can of Sprite, most preferably 7-Up, a tall clear plastic cup, and several raisins, preferably fresh raisins. The clear carbonated soda is used as the carbon dioxide bubbles, the clear plastic cup is used to show what happens when the soda causes the raisins to dance, and the raisins are used to show buoyancy and how the …show more content…
The procedures that were used to demonstrate “Dancing Raisins” are quite simple. The first step is to pour the can of carbonated Sprite or 7-Up into the plastic cup. Then, the second step is to drop six or seven raisins into the plastic cup. Lastly, the final step is to watch what happens to the raisins. Dancing raisins consists of a few concepts that are carbon dioxide bubbles and buoyancy. The first concept is carbon dioxide that is created when the beverage is put into a can in high pressure of carbon dioxide gas. When you open the can, the carbon dioxide rushes out, a sound can be heard which is the carbon bubbles. The movement of the raisins when they bob up and down are caused by tiny bubbles of carbon dioxide gas that stick to the raisins rough surface, making an attraction. The bubbles increase the raisins volume but it does not affect the mass. The
