To estimate your breast weight using this method, you’ll be measuring the weight of water displaced by your breasts. Start by getting a bowl that’s big enough to completely submerge one of your breasts as well as a deep tray or baking dish. You’ll use the tray to catch the displaced water from the bowl. You’ll also need an accurate scale for measuring relatively small weights, such as a kitchen scale. A small bucket or cooking pot should also work if you don’t have a bowl that you can easily fit one of your breasts into. Since you need to determine the weight of the water that spills into the tray, get the weight of the empty tray first. After you weigh the displaced water, you’ll need to subtract the weight of the tray to get an accurate weight.  Use a scale that can measure in ounces and fractions of ounces. This will help you get a more accurate weight than if you used larger units of measurement, like pounds. Write down the weight of the tray so that you don’t forget it! After you weigh the tray, set it down on a level surface and put the bowl in the middle of the tray. Fill your bowl with water all the way up to the brim so that some of the water will spill out when you lower your breast into it. For your own comfort, you may wish to use warm water. After you fill the bowl, position yourself over the bowl and tray and slowly lower 1 breast into the bowl. Lean forward enough so that your entire breast is submerged in the water. You may need to rest your ribcage very lightly on the rim of the bowl, but try not to push down too hard so you don’t accidentally displace excess water.  Some of the water should spill over the sides of the bowl into the tray. Do this without a bra on so that the bra won’t absorb water and interfere with the measurement. When you’re done, carefully lift your breast out of the bowl and remove the bowl from the tray. Put the tray with the displaced water in it on your kitchen scale. Subtract the weight of the tray from the result.  Be careful not to spill any of the water from the...
