I went to PDF in the game and to Beckett's Quarry, and I found out how to do the glitch in it. This is how to stand on Lava.
Watch Video I Made Here. If link didn't work it is:

If any one found this glitch before and told how to do it please tell me. I do give credit to the person that did do a video on how to do it.
