The twins were almost 46 months old at the time when they encountered this tornado display from the Exploratorium placed at SFO near gate 89 for promotional purpose back in 2001. There is a fan on the ceiling of the contraption to move the air upward. The four pillars are hollow each with air blowing out of a column of holes. These jets of air from the pillars are pointing a little off centered to create a shearing force to the column of air while it is being sucked upward. The smoke generator at the bottom makes the vortex more visible. This tornado demonstrator is one of many hand-on scientific displays at the Exploratorium in San Francisco.
