An Unethical Life Pro Tip (or ULPT) is a tip that improves your life in a meaningful way, perhaps at the expense of others and/or with questionable legality. Share your best tips you've picked up throughout your life, and learn from others!
ULPT Rules:
- Tips must be unethical, tips that are ethical will be removed.
- Tips must provide some benefit to you.
- Post titles must begin with "ULPT" or "ULPT Request", and should be descriptive. The title should explain the gist of the ULPT without needing a description. Post that are walls of text will be deleted at the mods discretion.
- No tips about rape, murder, suicide, or any tips that violate Geneva Convention laws.
- No tip lists, each individual post should be about a single tip. This includes links to articles that list tips.

Get a cheap plastic form- a large plastic plant pot would work well. Line with tinfoil or plastic wrap. Cut a large hole in the bottom of the pot and the tinfoil. Turn it upside down in the spot you want the bollard. Fill with quick-set concrete. When the concrete is set, take the pot with you so you can make more, the foil should keep it from sticking. If you can work out a way to get some metal wire into the concrete form before you pour, it'll be much stronger.
Downsides to this could be getting enough concrete and water to the site- shit is heavy. Also, while it should be set in an hour or two, getting knocked by a car right away might kill it.
I looked it up and an 80 pound bag of concrete needs about 3L of water. That all seems doable.
Anyone know how long it would take to set?
I would expect it to be set enough that you could remove the form after a half hour to an hour
Make sure you get fast-setting concrete. It’s the difference between the time being about an hour vs about a day.
