Bernoulli Wind Lab — Laue Labs engineering pack

Bernoulli Wind Lab

Laser-cut venturi tube and airfoil demos with a guarded 12 V PC fan and either a simple manometer or paper lift demo. Learn Bernoulli’s principle and continuity—with honesty about when the model breaks down.

$7 Physics

Digital guide + cut files + BOM + code · Parts sourced separately · Ages 8–14 with adult help

Pack contents

  • 3-layer venturi sandwich, 8-slice airfoil, stand SVGs
  • Mount fan + manometer / paper lift guide
  • First-principles: continuity, Bernoulli, airfoil caveats
  • Experiment cards
  • Verified BOM (~$29–79 hardware)

Typical hardware cost

Default structure is laser-cut birch plywood with real fasteners and hobby electronics you can source—honest BOM, not mystery modules.

  • ~$29–79 in typical parts (makerspace cut toward the low end; mail-order toward the high end)
  • Digital pack price ≠ hardware

The $7 pack is the digital guide + cut files + BOM + lessons + code, plus printable Builder's Corner build journal pages. Hardware is sourced separately — see Where to get kit materials. Buy with Stripe is live below.

Learning outcomes

  • State continuity: A·v roughly conserved
  • Use Bernoulli qualitatively along a streamline
  • Observe Δh on a manometer at the venturi throat
  • Discuss real airfoil physics beyond “Bernoulli only”
