Last week I did an expermient which goes as follows, I boiled some amount of water, and then put in a small piece from an uncooked thread of noodle, first of all it went right down to the bottom of the boiling vessel stayed there a while and then came back up. One would obviously think that when first it sank why it rose now ?
On watching carefully I observed that the small piece of noodle was covered with not water but air bubbleswas covered with air bubbles, it was like someone had wrapped it in bubble wrap and let it float on the scalding water. Now the question comes that why did the bubbles accumulate around the noodle such that it started floating ?
