  Sometimes it takes a while to set the experiment up right. I study plasma… its an electrically charged gas and it often behaves in confusing ways. You have to spend a bit of time working out what it’s doing! But we usually get there in the end 🙂 Nothing ever went really wrong … I haven’t blown anything up yet 🙂
