F4-63: MARIOTTE'S BOTTLE

PURPOSE: To show the range of water jets from different heights along a water column.

DESCRIPTION: Five water jets emerge from the tank at equal vertical intervals, with the height of the water at that same interval above the top jet. The range of each jet is measured at the level of the bottom of the container. The center jet has the greatest range; each pair of jets having the same vertical distance from the center jet has the same range, where the range is less the further the jet is from the center.

Click your mouse on the photograph above to see a video of the action.
