gas trap

On Thursday, it was science and we got a paper that was called gas trap there was a place to cut so I cut it. 

We got ot water in our cup and we waited for about 2 minutes and we saw stem on the glass sides and the we got a lid than closed it and we wrote what we saw inside.

So cut part it had words and suppose to hold it on the other side and try to read it. So after the experiment we had a talk and we were talking about water vapour, so after the talk we were done.
