From the relay upwards, it looks like a panicky frog..
It's connected to a battery. We'd all panic.
That takes me back to secondary Biology classes when the tutor killed and cut open a frog, he then dropped a spot of acid on it's heart and it started beating..
Please don't try this at home..
Needless to say the girls in our group were not too enamoured with this experiment.
Sorry for the drift it's all Eric's fault
