Model boat kits are widely available at hobby and craft stores. many of these are scale models of existing craft such as naval ships, sailboats or historic ships. these models are intended for display and therefore do not usually float. use items from around the home to make a model boat that does float.. Build boats and float them down the river – floating homemade boats down the river was a favorite when i was young. we spent hours creating boats that we hoped would make it past the bend and out of sight. if your kids are little, use sticks just like winnie the pooh.. Well, wood is lighter than water, so it floats, but that has very little to do with why a boat floats. you could make a boat out of just about any material that was rigid enough to hold its shape, and strong enough to not crack under the pressure a boat is subjected to, and, if built to the correct dimensions, it would float..
Make the boat's basic hollow shape. with a moldable material such as clay or sculpted material such as wood or styrofoam, build a canoe-like shape by first forming the material into a long, thin log, then flattening one edge by pressing it flat, sawing or sanding it.. A huge boat, on the other hand, will float because, even though it weighs a lot, it displaces a huge amount of water that weighs even more. plus, boats are designed specifically so that they will displace enough water to assure that they'll float easily.. Now most boats don't operate in quite the same way as submarines. they don't sink, but they don't exactly float either. a boat partly floats and partly sinks according to its own weight and how much weight it carries; the greater the total of these two weights, the lower it sits in the water..
