Why does a straw fall out of a glass of coke?

What happens when you put a straw in a glass of Coke or any other carbonated beverate, is that bubbles of carbon dioxide form on the straw and cling to it, and since these are lighter than water, they tend to lift the straw up out of the Coke; when it is lifted high enough it will become unballanced and fall out of the glass.

Why do bubbles appear in a glass of water over time?

As you leave a glass of water out, it warms. As it warms, various gasses (CO2, O2) become less soluble in it. Hence they escape from it in the form of these bubbles!


Are the air bubbles that form on a straw submerged in liquid formed from oxygen that is already in the water or are they carried into the water by the straw as it is submerged?

The straw gives energy to dissolved gases in the liquid, be those gases oxygen, or whatever. The energy given to the gases causes those gases to come out of solution in the water, and to collect on the surface of the straw.

What happens when you submerge a 9 volt battery upright in a glass containing water and half a teaspoon of salt?

When you submerge the glass, oxygen bubbles form on the positive outlet, and Hydrogen bubbles form on the negative outlet. Soon a mould sort of thing starts to form on the water. Try it out, it is an awesome experiment. PS- All this stuff only happens if you place 1/2 a teaspoon of slat in the glass and stir it in, the submerge the battery. PSS- Make sure the whole battery is submerged.
