To do this glitch go to training and go to any of the firing range's. Once your there, place each dummy in a stack in a row of one. Once that's done place a target on top of the stack. Then teleport your worm on top of the target. Once this is done, set the water level up to your worm, then bring it down again. WHOA! Your worm is floating! Doing this repeatedly will get you worm even higher!
