Bernoulli Effect with a Leaf Blower

PIRA 2C20.31

Leaf blowers produce an air stream that moves at over 120 MPH.  This is ideal for a variety of Bernoulli effect demos.  Large balls, pop bottles, screw drivers, and small furry animals can be levitated within the air stream.  Beach balls work particularly well in a room with a tall ceiling.  A little water inside a smooth-bottomed 2l plastic bottle provides enough blast for a for an impressive demo, as shown at far left.  Streams of toilet paper can be suspended 30' in the air.  The removable PVC attachment shown in the picture at near left allows rapid and convenient dispersal of toilet paper.
