When i went to global village I went on this cool roller-coaster. i call it the demolisher. it felt like it was as fast as sound . when you go down you feel like you’re going to fall. you’ll feel like you will die. but it was as good as having a psp. i went twice. i tried front seat and back. the difference is that the back jumps when you go down, and the front you feel like you’re going to die. you feel like you are going to topple over. but when people make them , they have to manage the angle of how is the slide going to come down. they manage the age limit and the size of the roller-coaster. i heard once the didn’t do it and some one fell 500m heigh. ouch!!!!!!???
