- When you want to get the content of a bottle (like a Ketchup bottle), don't shake it up and down. First, place it horizontally and shake it up and down: this will make the sauce fall on one side of the bottle, and then place it vertically and shake it up and down. The sauce will slide down better and you will get out more of it and faster.
- Don't you hate it when the end part of the belt sticks out in the air, with nothing to pin it down to the pants (or the belt)? Many times those loops in the belt or pants are not located in the right place to catch that end of the belt. It is even worse with a dress which has no belt-loops at all.
So here is my solution: Take a rubber band women use to tie their hair (a small thin one, in the same color as the belt; not red and bulky). Make a double loop of it if necessary to make it wrap tightly around the belt, and slide it onto the belt. You can easily move it anywhere on the belt and use it to pin down the edge of the belt. Flawless finish. :D
- Vacuum cleaner? Forget it. Get an iRobot vacuum cleaner. They perform better than a normal vacuum cleaner and vacuum on their own.
- This one is probably well known, but it is useful so I'll write it just in case.
Opening a jar: The problem with those jars is that they are closed with vacuum. This creates a force that pulls the top onto the jar. It gets worse when the jar is cooled down since the air pressure inside the bottle drops even more, making the vacuum effect stronger.
Solution: Create an opening for air to go into the jar. Slide a thin yet strong knife (or metal object) under the side of the lid, and slightly push the knife into the jar (or push the edge of the top to the side, away from the jar) to create an opening. This will let air in, cancel the vacuum and allow you to open the jar without any effort.
That is all. I'd be happy to get a feedback from you if you've tried it, or if you have similar useful tips.
