Description

Science First Wind Tunnel along with an accurate balance illustrates the effect of lift in action. An electronic balance is placed under the airfoil post and the fan is turned on which makes the apparent weight of the airfoil decreases with lift. It includes acrylic tube with airfoil, built-in fan, plastic housing, banana jacks for power and instructions. Requires small digital scale, low voltage power supply, and source of smoke, not included.
