NEW VIDEO where I built a fluidized air bed in a hot tub with sand and then tested the principles of buoyancy with my nephews... by throwing them in. https://goo.gl/gvJrDy | Mark Rober

This is fluidized bed coating — where powder acts like liquid. #FluidCoat #SmartFinish #fblifestyle | Lara Amélia

Fluidized bed coating uses air to suspend fine polymer powder so it behaves like a liquid. A metal post is preheated and dipped into the bed, causing the powder to melt and fuse instantly on contact. This creates a smooth and uniform coating without drips or uneven buildup. The thickness of the coating is controlled by the temperature of the metal and the time spent in the bed. Because the powder melts immediately, it bonds tightly to the surface and wraps around edges and corners evenly. This m
