1. Step 1. Boomerang wings — is part of — Boomerang. Two wings with an aerofoil profile.
2. Step 2. Boomerang — uses — Lift. The blades are wings that create lift.
3. Step 3. Lift — uses — Venturi effect (Bernoulli’s principle). The pressure difference above and below the wing (simply put — Bernoulli).
4. Step 4. Venturi effect (Bernoulli’s principle) — is used in — Carburettor. In the throat of the venturi the pressure drops and draws in petrol.
5. Step 5. Carburettor — has part — Valve. A throttle valve in the carburettor sets how much fuel-air mix reaches the engine.
6. Step 6. Valve — is part of — Gas lamp. A gas supply valve.
