Model for demonstration of Bernoulli's principle.
The airflow source is placed in the wooden base of the airway, the air gets to the top. The mouth of the duct opening is directed downward. The device is a wooden disc. The flowing air is moving faster than the ambient air, thereby reducing pressure on the upper part of the disk to hold it in the air.
Material: wood, plastic and a source of compressed air
Power supply: 1500 W / 220V
Dimensions (cm): 50 x 50 x 50
