• The Airzooka is a demonstration kit that consists of
    a hollow plastic cylinder mounted on a handle. One
    end of the cylinder is opened as a hole whereas
    the opposite one has a membrane surrounding
    the whole surface. This interesting swirl starter
    sends air cluster to the environment with its flexible
    structure at the back and air power. The scientific
    name is a vortex generator (also named as vortex
    ring launcher or vortex cannon) since the ball of air
    (or fog) that shoots out is really a vortex. The vortex
    is created because the air leaving open end of the
    cylinder (from the hole) at the middle of the hole can
    go faster than air leaving around the edge of the
    hole. As you hit the membrane, it pushes air into the
    cylinder. As a result, the volume inside the cylinder
    decreases and pressure increases. That pressure
    increase pushes some of the air out of the hole at
    the opposite side. The smaller the hole you cut,
    the greater the velocity the air (fog) will come out
    when you strike. This demo can be used to show
    that air is also a material and to show the effect
    of Bernoulli. Blow out the candle remotely, create
    interesting air swirl, create mist circles with the help
    of mist machine and wake up the sleeping person
