The first picture shows all the materials we need, and the second one how it should end.
Here are some videos to show how it's done:
1. First, we put vasseline in the stopcock, and we attach it with the rubber bands.
2. We put the stopper on top, and fold it so that no air can get in or out.
Your introduction needs a bit more detail so you can explain why we are doing the lab session. Please explain what you are doing in your videos so that it is easier to understand what you are doing. Your written method also requires more detail.
