Bremen Universum

Something that I learned from the Universum was how circuits worked. When I first tried to figure it out, the station quickly gave me a red light which represented that I blew a fuse. During the second attempt, it was explained that to me that the positives and negatives needed to be matching (bottom hill and upper hill if I remember correctly). I eventually tried the harder solutions which required connections to more than just one light like the first one that I tried. Thank you Liz for explaining it all to me!
