That's a great clip... obviously developed for school kids, but there is no way you'd be able to use it in a classroom in the UK. 'Big fat guy' is so politically incorrect here these days, you might give some kid in the class a complex and cause him to develop an eating disorder and then he would be able to get psychiatric help on the national health for the rest of his life, never be able to work and sue you for damages for being 'fattist'!

Multiple levers with in a lever in conjunction with multiple levers for propelled momentum & motion of mass proves to be much to difficult for some peoples comprehension & understanding . learning from hind site I'd have to say that the topic is taboo in regards to horseshoeing & will only serve by bringing you disrupt regardless of your correctness.
