Answer:
Here are the correct order of steps to make your own disposal jar to disinfect lab tools:
Obtain a disposable plastic container (like a disposable cup or empty water bottle).
Fill the disposable plastic container halfway with isopropyl alcohol or common rubbing alcohol.
When finished with an inoculating tool, put it in the disposal jar and let it soak for at least half an hour.
Dispose of the tool and empty disposal jar in the trash.
Do not pour alcohol down the drain. Instead, follow proper disposal procedures and guidelines for hazardous waste in your area.
