How can you float on water?

lay on your back and hold air in your lungs extending the arms and legs. dont have to hold your breath really. take short breaths out and longer breaths in holding for 2 or 3 seconds

fill water balloons with different amounts of water and drop them at the same height to see if they fall differently.  =)

DENSITY is the key.\n\nRemember, an aircraft carrier will float in water because it is less dense than the water.  To calculate density, divide mass - kilograms (m) by volume - cubic meters (v).\n\nPure water at 25 degrees Centigrade has a density of 998 kg/m^3 so any object with a density lower than this would float.  Higher would sink.\n\nInteresting note:  If you could find a body of water large enough, the planet Saturn would actually float in it since it is less dense.

buoyancy--\n\n\nIn physics, buoyancy is an upward force on an object immersed in a fluid (i.e., a liquid or a gas), enabling it to float or at least to appear lighter. Buoyancy is important for many vehicles such as boats, ships, balloons, and airships.\n\n\nfor more info \nu can c this link--\n\nhttp://en.wikipedia.org/wiki/Buoyancy

The reason you floated better in the ocean is because the density of salt water is different than regular water. \n\nThink about keeping your hips high. If you're on your back, press the back of your neck/head to the bottom. If you're on your stomach, it's very natural for your legs to sink slightly. Just keep your hips up!

Your lungs will do the same job as the beach ball.  If you can relax and keep air in your lungs, you will float.  Try in shallow water, take a good breath, relax and lay back.  You will be fine.

anyway, as u know,  any leaf will float on water because the cells (mesophyl) have spaces all between them. the inside of a leaf is like a heap of baloons pressed together a little - they touch only by sides. this is to allow passage of air necessary to photosynthesis, too. the oily appearance of the "skin" , the epidermis of the leaf is good to make it last and live long and not go rotten in water. some plants that float really have one side hydrophilic and the other hydrophobic so that they dont flip the other way up, which would be undesirable. write me email if u have other questions as u study more of this

They are made of wood, which floats because it has a lower density than water.  If you made a ship out of solid gold, it would sink, for example.

firstly b4 answer...some commonsense (sometimes not so common sense) safety. When you are learning always have an experienced friend & adult supervision (if applicable, ie. if you are under-age) this is critical!!\n\nSafety out of way now for answer :)\n\nLots of ways...\n\nGo to a swim teacher or...\n\nIt's easy to go with a friend to pool and use a pool-noodle under your arms, once you can float with this, use your friends hands instead of the noodle, get them to have there hands at your lower back (centre of gravity)and slowly ajust your body till you feel balanced.\n\nWhen you feel like you are floating get your friend to slowly lower there hands away from you till you are floating all by yourself.  Remember that floating is not about freezing but about slow suttle movements to maintain balance.\n\nHint:\nDo everyhting at your own pace and work on blowing bubbles and pretending to sit on recovery (backside down 1st instead of feet first towards ground)so you dont panic and get a monthful of water.\n\nGood Luck (sorry for long answer, important to do properly)\n\nI'll repeat for my own concious..Friend and adult supervision (if applicable) are critical!!

You need to rotate your body. When you start your recovery (hand starting from your hips moving to start your stroke above your head), initiate the movement with your shoulders. Rotate your shoulder out of the water, to under your chin. Then start your hand moving up above your face, turning your hands and placing your pinky into the water.  This movement will help to rotate your body. Don't "shrug" your shoulders to your ears. Visualize your legs following the rotation of your body, and visualize your flutter kick rotating from one side, up and over to the other side. This rotation will make your body more hydrodynamic and prevent your legs/hips from wagging side to side. \n\nA drill you can practice is the one arm back stroke. Do a lap stroking with only one arm. The arm that you are not swimming with rests at the side of your body. When you start your pull (in the water) you should be on the side with your almost all the way in the water. You should feel like you are doing a side stroke. Your kick will be a side flutter kick. When you do your recovery, kick on your back. Once your hand recover back to above your head, glide and maintain your balance. Start your pull again when you feel balanced and stable.

you can go until you hit water

what is incredible about swimming is that it is horizontal exercise,and like flying in mid-air! For some people it might be the only horizontal exercise they ever get.. Because you are in the water you are able to move more weight with less resistance,and exercise your cardio-vascular system ( if you progress into laps,especially) A great body workout!!

Any object will float as long as it displaces a volume of liquid that is more massive than itself. Take the aluminum boat and fold it into a block of aluminum and it sinks. But due to the shape of the boat, the mass of the aluminum,plus you, and your fishing gear, is still less than the volume of water pushed aside by the hull of the boat. So, you float.

The question is...Can anyone walk on water???? NOT!!!!!!

NO!!!  Many people tell me "Everyone can float on their back."    I tell them I don't float.  So they proceed to tell me how I do it wrong.  \n\nSo they (even swim instructors) get me to float on my back and let go, my legs start sinking and slowly the rest of me sinks. Until my nose is underwater and where I finally stop sinking, but then I can't breathe.
