Scientific research at home is not very difficult; just drop a Mentos mint in a bottle of diet coke to cause a giant eruption. This easy experiment illustrates perfectly a very important and daily physical phenomenon called surface tension: the surface of a liquid behaves like an elastic layer, caused by attractive forces (Vanderwaals forces) between molecules in the liquid phase. Surface tension is the reason why air bubbles constitute in our bottle of diet coke: water molecules cluster together to form a layer around the CO2 gas. After the candy has been thrown in the bottle, the Mentos mint will dissolve, disrupting the structured arrangement of the water molecules at the sides of the bubbles, by which the gas will expand. Similar effects can be seen if you boil potatoes or pasta: boiling over can be explained by the fact that the starch interrupts the structure of the water molecules around the gas bubbles in the boiling water, due to the surface tension. So a simple experiment of combining diet coke and mentos shows the importance of surface tension as a physical phenomenon.
