one of the most interesting thing that i learn  is that   sound can travel through solid,water and gas and i found out that there  is no sound on the moon i though there was i found that online it was a really interesting thing.and i learn that sound can go through a brick but that was kind of known but it can even travel through solid things that's why i am  saying that but it was really fun learning abute this.
