***UPDATED*** Updates Include easy and quick to print with new design. Also easy to turn and grip! This is a fluid dynamics demonstration. It is demonstrating how motion effects liquid/fluid MaterialsTwo bottles (water and coke bottles work)3d printed tornado pieceWaterExperimentGrab you bottles.In one of the bottles a water into it make it so it fills the bottle up to about ¾ of the way.Screw on your 3d printed piece to the bottle filled with water.Screw on the other bottle (no water in it) onto the other side of the capFlip the bottles over fast and move it in a circular motion.Watch and enjoy your creation!Explain: This works because the 3d printed piece is making it hard for the water to travel though and making in a narrow space, and because of the spinning it makes it so the water is almost “pulling” up against the sides of the bottle making it have an effect of a tornado.
