No, but there is a few things that can do something similar.
1. Environmental Atmosphere.
I had an atmosphere thing where it would cause really low gravity. I don't have it anymore, but I assume it's still out there.
2. Zone Bricks.
You can get the Zonebrick pack and use the Zero-Gravity zone and bounce around in it.
3. Playertype: Bouncy Player.
There is an add-on that gives the player a bouncy playstyle once getting the Playertype.
4. Weapon: Bouncy Gun.
There is a new gun that has bouncy properties. The bullets bounce around everywhere. And a cool little effect as a bonus: The gun itself bounces too once dropped.
That's all I know that has low-gravity, No gravity and bouncing properties. I hope this helps you. Have a cookie.
