so the insanity level of this jump was up there, for sure. >> do more, you can't even see it. >> pour the lighter fluid. hell yeah! >> as chris tries to light the bush on fire, cameras roll from above and below. >> power that all over there. >> jay jones is one of the teens filming. >> i was in between the bush and chris on top of the cliff filming. i guess mainly the only thing i was worried about was getting the bush lit on fire. i've seen chris jump over that bush before. >> you can hear jay shouting to make the fire bigger. >> that's not enough. >> first we tried lighter fluid. and it wasn't making a dramatic enough effect on the bush. so then it turned to the gas. >> now you got to light it again. >> we struggle for awhile to get it lit. >> just before chris is about to jump, spectators on a boat offer up another challenge.
