Fondant icing a supersaturated solution until nucleation occurs. While the solution is supersaturated, if a cook puts a seed crystal (undissolved sucrose) into the mix, or agitates the solution, the dissolved sucrose crystallizes to form large, crunchy crystals (which is how rock candy is made). However, if the cook lets the solution cool undisturbed and then stirs it vigorously, it forms many tiny crystals, resulting in a smooth-textured fondant. Fondant icing Fondant icing, also commonly referred to simply as fondant (, ), is an icing used to decorate or sculpt cakes and pastries. It is made from sugar, water, gelatin, butter, and
Metal foam titanium foams are common for their tensile strength, corrosion resistance and biocompatibility. The back legs of Siberian Husky named Triumph received foam metal prostheses. Mammalian studies showed that porous metals, such as titanium foam, may allow vascularization within the porous area. Orthopedic device manufacturers use foam construction or metal foam coatings to achieve desired levels of osseointegration. The primary functions of metallic foams in vehicles are to increase sound damping, reduce weight, increase energy absorption in case of crashes, and (in military applications) to combat the concussive force of IEDs. As an example, foam filled tubes could be used as
