level 70

Please can you help me with this . ive tried everything

Place conveyor belt left of the other, just a small gap. Connect them up using the battery motor and gears so that they are both running to the right. Place lamp just left of conveyor belts and directly under weight (the weight will operate this and rest on it). Place magnifying glass to left. Place cannon in gap between 2 boards facing right. Run fuse from magnifying glass to cannon.
Weight will fall down sit on and operate lamp, fuse will ignite cannon which will push balloon and weight onto conveyor belts, scisorrs will cut rope and balloon will rise.
