There are a huge number of different objects in the world, and it is often very difficult to understand what this or that thing is for. But it is good that there are ubiquitous users who can solve any riddle. Take a look!





1. Made of aluminum, height about 15 centimeters. Comes apart into 3 pieces



This is a training piece for a lathe operator. It has many different physical characteristics that can be machined on a lathe. The sealing rings, the threads, the rounding at the end, the two corner areas are different forms of constriction.

2. This is a metal container that has a raised and lowered top. It's pretty heavy





An old-fashioned hand-held fire extinguisher, from around the 1940s. These extinguishers were common during World War II and were often used for civil defense.

3. What is that gold-plated metal thing? It's really heavy, with a little hook on the standing part. Found in an old house



This is an antique brass pocket watch stand.

4. Hand tool. About 20 centimeters long, made of brass and steel



This is a caliper for carpenters or boat builders to measure the size of a board.

5. A large glass container with holes in the lid. Screw cap with holes, but it doesn't come off



A vintage glass cocktail shaker with holes built into the top for a strainer. It usually has a removable lid that covers those holes for shaking, and then you take that little lid off to strain your drink through the strainer.

6. Found while cleaning out an old house



This is a mold for small sugar cubes. You need small silver tweezers to open it.

7. I found this weird metal thing, it's pretty heavy and about the size of a pen, I think you can open it

8. A black plastic cone, hard, with a hole at the wide end and a sharp end at the other

9. A small red plastic bucket with a small curved metal rod inside that can be moved back and forth



This is a propane tank cap. In some countries, it is mandatory to install one on gas tanks when not in use. If you transport a gas tank without this thing, you will be fined.
