AEROS box

This is a fluidized air bed! if you don't know what that is, it is a box that uses air pressure to make sand act like a fluid by pushing air from the bottom. It's great for science projects and for fun! this is not a new thing, it's just not widely known. I used an air compressor to put air in it, but you can use whatever you want. WARNING: fine sand is recommended for best results. Mark Rober did an entire video on this, and if you want more “juicy physics" you go there.Boost MeIts free
