I can't figure how to solve B18 after it was changed. I know I don't have to destroy the upwards conveyor belt from reading a different comment but still have no idea what to do. I believe I need to get one of the explosive gas cans away from the left wall and use it as a platform to stand on to get to the next level but I feel like the method I'm trying to use where I blow up a block in the upper right portion of the nine to get a space to push the other gas can forwards isn't possible because I don't have enough platforms.
