Isadore Rabi at one point took that notion seriously and asked (something like) "If a single particle can go zipping along without inhibition, why shouldn't an ordinary clay brick just jump up in the air?"
Then he did the math. One problem is that in a clay brick there are a whole lot of particles zipping around in different directions, so they cancel each other out. Thre's a bit of vibration going on -- the temperature, see -- but you don't get more than a very few close to each other heading in the same direction at the same time. And all of them? Wey-yull, let us calculate...
Turns out that with reasonable assumptions all the particles in the brick are going to get together and head in the same direction just by chance, uh, every now and then.
Rabi's informed guess is, a normal ceramic brick, like what you buld a house with, will jump one foot in the air, quite spontaneously, roughly once in every ten-to-the-sixty-fourth-power -- 10^64 -- times the age of the Universe.
Plus or minus, obviously.
