Tutorial: THE HAMMER SLAMMER - In forge mode (or any other mode that you have access to a mongoose and gravity hammer) turn over a mongoose so it is upside down. Jump on the mongoose and then crouch. While crouching take out your gravity hammer and press the R Trigger (Fire button). If done correctly you should fly into the air.
