Science Explained on Instagram: "Do follow @world._.education - When you push an upside-down bucket into water, the air inside gets trapped because water can’t fill it completely. The water pressure holds that air in place, creating a small pocket to breathe. This same idea was used in old diving bells, which helped divers stay underwater longer by carrying air down with them. Warning ⚠️ - Don't try this for fun. The pressure would be high enough to damage your brain! #scienceexperiment #physics
