I have done this type of ride at hw and the lighter the tube, the lower you go. With more weight, you can almost reach the jets that shoot down. Also, if these two kids were across from each other, it wouldn't happened, or rarely happened. AT hw, they only allow 2 adults per tube. With kids, they make sure there is a adult on the tube and the kids hold onto the handles.
