Drought-Stopper Drought-Stopper ExplanationExplanation Mr. Fisher’s drought- stopper is also referred to as Mr. Fisher’s drought- stopper is also referred to as

a siphon. As the water was poured into the beaker, a siphon. As the water was poured into the beaker, the water began to fill the tube by entering the the water began to fill the tube by entering the inflowinflow end of the plastic tube. The tube continued end of the plastic tube. The tube continued to fill until enough water was added and the level of to fill until enough water was added and the level of the water was above the loop in the tube. At this the water was above the loop in the tube. At this point, the effect of point, the effect of gravitygravity caused the water to flow caused the water to flow out the out the outflowoutflow end. The water continued to flow end. The water continued to flow out of the tube until the water level dropped below out of the tube until the water level dropped below the the inflow inflow end of the tube. The water that was end of the tube. The water that was previously in the beaker before, was pushed out by previously in the beaker before, was pushed out by the the siphonsiphon effect which requires the effect which requires the outflowoutflow end end to be to be lower than the inflow lower than the inflow end of the tube.end of the tube.
