Floating Ping-Pong Ball Vortex Tunnel

15 mins Ages 1-3 Indoor

A playful, screen-free adventure designed to spark curiosity, sensory exploration, and fine motor skills for kids aged 1 to 3.

Materials Needed

  • • Hair dryer with a cool-air switch (1 unit)
  • • Table tennis ping-pong balls (3–4 units)
  • • Cardboard paper towel tube (1 tube)

Pro Tips

  • → Hold the hair dryer pointing vertically upward and set a ping-pong ball into the airflow; it will levitate in mid-air.
  • → Let your toddler drop a second ball into the airstream to observe mid-air collisions.
  • → Slowly tilt the hair dryer up to 20 degrees off-center to demonstrate how the low-pressure air pocket traps the floating ball.

Safety First

Ensure hair dryer is locked strictly on the COOL temperature setting.
