MENTOS GEYSER CARBONATED DRINKS AND MENTOS
PROBLEM STATEMENT:
WHAT IS THE EFFECT OF MENTOS ON CARBONATED DRINKS?
BACKGROUND INFORMATION:
The soda contain sweeteners (sugar or artificial sweeteners) flavoring, water and preservatives. Carbon dioxide (CO2) gas is added to the soda trough a high pressure process that causes the gas to dissolve into the liquid, when the soda is opened the gas is relieved and the dissolved gas escapes. In soda, the water molecules cling together around the carbon dioxide gas bubble, when the mentos dropped into the soda, the gum arabic in the coating of the mentos weakens the attractions of the water molecules around the CO2 bubbles. As soon the mentos hit the soda, the carbon dioxide forms more bubble in the tiny pores that are all mentos surface. Couple this with the speed at which mentos are sinking to the bottom of the bottle and an eruptive blast occurs as the CO2 is released and breaks free taking much of the liquid with it.
HYPOTESIS:
If carbonated drinks cause a trajectory when mentos are included, then diet coke will cause the tallest height trajectory.
MATERIALS:
*1 2 liter bottle of sprite
*1 2 liter bottle of diet coke
*1 2 liter bottle of sparkling water
*3 pack of mentos
*tape measurer
*tube
PROCEDURE:
1. Go out an open space.
2. Line up the bottles.
3. Put the measuring tape behind the soda to measure the height of trajectory.
4. Put 8 mentos into the open bottle of soda.
5. Take pictures and record data.
6. Repeat steps 2 to 5 for the remaining sodas.
7. Record all data.
VARIABLES:
INDEPENDENTS: type of soda
DEPENDENTS: type of soda, height of trajectory
CONSTANT: volume of soda, same room temperature, mento’s style of entry, same numbers of mentos.
CONTROL EXPERIMENT: put mentos in carbonated water.
DATA: This data revealing the effects of mentos on carbonated
