With the narrator it kind of reminds me of those scammer trolling videos, haha.
I couldn't do the red ball one (I thought it might be a trick and it was actually the antenna but that didn't work either), so I had to just restart on that one! :(
on the red ball one you have to drag and drop and green square on the antenna (also thanks for the feedback)
Oh it WAS a trick after all. I just didn't think of moving the box there, almost! :P
