Did you get it right?
This canning-day scene includes two items from a later era.

The two mistakes are the disposable plastic water bottle and the wireless earbuds case.
Here is why

- Find the earbuds case beside the jars.
- Both are modern objects.
Why people miss it
The jars and kitchen clutter make the modern items easy to miss.
