LSSC Fields Wind Tunnel and Water Percolation Exhibits at the Innovation Fair

May 6, 2019

Hundreds of children and youth did experiments with our new vertical wind tunnel and water percolation apparatus at the May 4, 2019, Innovation Fair at the Bankhead Theater in Livermore. The wind tunnel interactive exhibit included the space-capsule parachute experiment and how density and size affect the wind speed needed to lift objects and blow them out of the tunnel. The water percolation interactive experiments included measuring permeability by the time for water to drain through various sizes of rock and measuring porosity by the amount of water needed to fill pitchers of various sizes of marbles and gravel.
