This new user, collab, is a collaberation of two existing users, ninjakitty7 and austin302. This scene was made with the two bombs that we each made a long time ago. 
     After some tweaking and gravity changing, this slightly unreliable bomb will go boom sometimes. 
Out of 60 test explosions (made possible by the UNDO button

 ) the bomb scored like this*:
20% explosions were full size, full power, even explosions
20% explosions were strange, yet cool half explosions
33.3% explosions were absolute failiures. 
21.6% were small explosions
 *IDK why this dosent add up exactly to 100%, but dont blame me, I asked the calculator. 
The bombs fail often because of the strange system austin302 suggested. The "frags" have lots of attraction and restitution, so it was really big, even, and will hold up in zero G. It is unrliable this way, but when it does boom, this space bomb packs a punch. 
And remember that this is a zero G bomb, so do not add a floor/plane.
Press enter , then undo and press enter, and undo and press enter until you get a decent boom
