Ever wonder why a crumpled ball of paper drops down faster than a sheet of clean paper when dropped from the same distance? My guess is your surface area and the upward resistance you face in the water. When you are in prone position your surface area in contact with the water is greater, hence greater resistance by the water. When you are curled up there is less surface area in contact with the water and hence less resistance. Hope it helps! Lionel Wong, Singapore Hi Noreen,

However, after a little thought over a big mug of coffee I wonder if it's possible that by curling your body up into a ball you are compressing your lungs which forces you to exhale slightly, thus making you less bouyant? What do you think? Good question! Jamie @Noreen

Hey Noreen,

Good question!

Maybe you can help me with a questions I've had for years (and I'm an experienced diver and AI). Given: an object is buoyed up by the weight of the water it displaces. I'm assuming that as a submerged diver, I displace the same amount of water whether I'm in a prone position or curled into a ball. Maybe this is a mistake. If this it true, then why, when I'm perfectly neutral in a prone position do I sink if I curl into a ball? Any light you can shed will be greatly appreciated. Thanks. Hi!!
