Bernoulli Aerodynamic Paper Airfoil Lift Experiment

25 mins Ages 6-11 Indoor

An engaging, screen-free learning activity that builds real-world creativity and critical thinking for kids aged 6 to 11.

Materials Needed

  • • White printer paper strip (5x20 cm) (1 strip)
  • • Plastic drinking straw (1 straw)
  • • Smooth sewing thread or monofilament line (1 meter)
  • • Clear tape and scissors (1 set)

Pro Tips

  • → Fold a paper strip off-center so the top surface curves smoothly while the bottom remains flat, mimicking an airplane wing airfoil.
  • → Thread a drinking straw horizontally through the wing center along a vertical guide wire.
  • → Blow a stream of air directly across the top curve: faster air drops in pressure, sucking the wing upward against gravity.

Safety First

Ensure hair dryer is set strictly to COOL setting if used.

Step-by-Step Instructions

1

Step 1

Fold a 5x20 cm strip of printer paper off-center and tape the trailing edge so the top forms a curved camber.

2

Step 2

Pierce two vertical holes through the wing and slide a short piece of drinking straw through as a frictionless bearing.

3

Step 3

Thread a taut piece of smooth thread vertically through the straw, taping the thread taut between desk and floor.

4

Step 4

Blow horizontally across the top curved surface through a straw, watching the wing generate lift and climb the string.
