We will need to choose the different types of balsa to complete different projects. One of the main factor to separate the type of balsa is the density. As we all know, the balsa is the favourite wood for model makers. And we will need to choose the different types of balsa to complete different projects. One of the main factor to separate the type of balsa is the density. It is not difficult to understand that the heavier the balsa wood is, the more pressure it can bear but at the same time, its flexibility will decrease. In order to find the density of balsa, we need to prepare several tools, such as measure tape, measuring pot, water, a scale for weighing and so on. Generally, the balsa woods with regular shapes are easy to estimate the density. We only need to find out their volume and weight, then divide the weight by volume we will get the density. For the regular shapes, such as the square shape, we can use the measure tape to measure the length, width and height. Use the scale to measure the weight of the balsa. When it comes to the balsa woods with irregular shapes, the work to estimate the volume is a little tough. Because there is no formula to estimate the volume of irregular-shape objects. We can weigh the irregular-shape balsa wood first. Take the advantage of measuring pot and we will find its volume. Pour moderate water into the pot and then submerge the balsa wood under water. You can calculate the volume from the rising water level. As long as we have known the density of balsa, it will be much easier to find the suitable materials for our projects.
