As these air bubbles become less dense, they rise because they weigh less than what’s next to them. WebThe bubbles will sink rapidly to the bench top or the ground – a plastic tray on the floor will reduce the mess (and possible slipping hazard) and should allow some bubbles to settle without bursting. These bubbles will shrink on standing as carbon dioxide diffuses out of the bubble faster than the less soluble air diffuses in.
