Blow-to-start siphon (venturi effect)

A simple tool to create a siphon using two tubes. It uses venturi effect to create a vacuum.

Useful when you want to transfer liquids and you don't want / can't inhale (ex: aquarium water, fuel...). You just need to blow into the tube to start it.

Tube inner diameter: 10mm

Tube outer diameter: 14mm
