Watch don't skip it it's awesome

Have you seen this sharp knife? Imagine with me... we can cut anything with it! But today, we are going to try something a little strange. I brought with me a regular bar of soap. See how the knife passes through it easily! It's as if it's cutting butter. The soap is divided into thin, equal slices. Nice, right? But why do we do this? A great idea for gifts! You can make it into different shapes, and add colors or perfumes to it. And if you don't like the shape, just cut it and reshape it! Share your ideas with me... What else can we cut?
