Water Bomb Jump

Water Bomb Jump is a glitch that allows Samus to do a bomb jump under water at any height without the use of Gravity Suit.

It is done by laying a bomb, getting hit by it while in morph ball, then unmorphing before Samus touches the ground again. Once you have done this you can bomb jump at any height you want/need.

One thing to note is that this state of Samus is lost if you touch the ground in morph ball at any point.

This is most commonly used to get Ice Missiles early in all NMG categories.

Here is a video example of it in action:
