To create a vacuum in a glass container, you can use a vacuum pump to remove air molecules from within the container. Place the glass container on a vacuum pump, turn it on to create a low-pressure environment, and then seal the container to maintain the vacuum inside. This will remove most of the air molecules from the container, creating a vacuum.
To effectively grow earthworms in a container, provide them with a moist environment, organic matter like vegetable scraps or shredded paper for food, and proper aeration. Keep the container in a cool, dark place and avoid overfeeding the worms. Harvest the worm castings regularly to maintain a healthy environment for the worms to thrive.
