Perforated Jar, Shows how a fluid changes behavior even under it's own weight, Each

Details

Model demonstrates how a jar filled with water shoots out at different rates of speed. The water at the bottom will have the most water above it, increasing the pressure and hence the rate of speed at which it spouts. The water pressure decreases proportionately for the two upper nipples. If the pressure is low, water won't escape at all.Unbreakable polycarbonate tubeColor: clearThree brass nipples positioned one on top of each otherMounted on stand
