Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

This is what I was referring to. There are a number of variations on the theme.

If you are really in a pinch:

Feed a length of hose into the source until only a small amount is left clear of the liquid.
Put your thumb over the exposed end, or otherwise make the end as close to airtight as possible.
Rapidly pull the hose out of the liquid, moving the end down to the destination container. The end must be below the top surface of the source, the further the better.
Release your thumb/seal. If you've done it all correctly, the hose will be nearly filled with liquid and enough of it will be below the surface of the source to start the siphoning process.

If the source liquid is too far below the opening for this to work with the length of hose you have, you can manually pump it far enough to start a siphon, by rapidly submerging and lifting the hose while alternating the closing of the top. Open top while submerging, closed top while lifting. You have to push down faster than what gravity pulls the liquid back down. Ideally, you're lifting fast enough to get some help from the liquid's own inertia when you reverse course.
