  Yep! During my last year at university I made a mistake where I put some of the wrong chemical into a test tube.. I could tell it was wrong because it went the wrong colour and when I put it into a machine to test for a chemical, it didn’t have any in 🙁 But things go wrong all the time in science and it’s OK for that to happen. You just have to try and figure out what went wrong and what you need to do to fix it 🙂
