How dose gum stretchability relate to bubble size?

Well the stretchability relates to bubble size because the strechier the gum is the bigger bubble it will be able to make.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
