warning you may break your limbs doing this

 first grab a trolley find a steep hill get video cam or mobile phone bring mate and wear a 3 pairs of underwear (only wear a helmet if u think your going to smash your face into 16 different pieces) then get your friend to film, jump into the trolley go down while friend records you may break an arm but at least you got it on video post on you tube and people will watch

Now you can get good views but first name it something like trolley stunt and edit it make some funny music to with it for best results bring another friend with a video cam and get it from 2 angles at once
