Thin pipe?
If a liquid is to flow through a pipe, a certain pressure difference must be present.
Investigate this with the following experimental setup:
A hole is drilled into the side of a PET bottle, above the bottom, from which a drinking straw protrudes horizontally. A stream of water is supposed to emerge from the hole and hit the ground from the bottle's elevated position. The length of the drinking straw is supposed to be variable.
- Investigate the dependence of the "throwing distance" of the water (horizontal distance from the point of impact to the end of the straw) on the free length of the straw. The water level in the bottle must be kept constant.
- Attach a photo of the setup.
- Also experiment with straws of different diameters.

various straws 🙂 The straw is horizontal and below the surface of the water, otherwise no water escapes. And the height of the water must be kept constant, so it must always be refilled during the experiment, so best make it two and mark the height of the water on the bottle. Start with the thinnest straw and drill so tight that it is also dense
