Hello, how are the crowds on Sundays? Is the place taking precautions due to Covid? Social distancing?

The crowd is going to be just about normal. There are several precautions in place to ensure that you are kinda separated from other groups of people while you view the exhibits.

They are taking precautions however people still like to crowd up together and they don't listen to the people who work there about social distancing. But it's kind of hard to social distance when you're in a building and there's only so many things that are open that are inside.
