You'll need to make a mold from silicone or alginate, with a rigid "mother mold" of plaster, fiberglass, or other sturdy material to help it hold its shape. Check here for some very good tutorials & materials:

Also, you might want to reconsider ballistics gel in favor of RTV silicone or urethane casting. Gelatin gets all melty and stinky pretty fast.
yea i dont care wat its made of but i need 2 no how 2 make the mold
In the link I posted, there are a ton of how-to videos and step-by-step photo sequences. That should give you all the information you need to get started.

Why ballistic gel?
You'd probably end up making a silicone mould.
