Step one Get to the object and go as far as possible to the object then lay down
Step two turn 30 degrees to the right
Step three Move the smallest amount to the left and try to crouch if you can keep edging your way until you can't
Step four reduce your angle to about 2-10 degrees and edge your way to the right after every movement then try to crouch once able to crouch move to the left
the idea is to get in between crouching and under the object
Step 5 when you are in between you should start to float up
