In a mod pack like FTB or Big Dig, have you ever needed vanilla slime balls to craft something but didn't have them?. Well me and alot of my friends have and while experimenting with MineChem i found a way to get a large amount of slime balls, all you need it one to start off with. First get the chemical decomposer and synthisiser then get 1 slime ball or if you have a mod like tinekrs construct or something craft 1 Magma Cube, then place the cube in the decomposer and take out the chemical needed to craft 1 slime ball you should have about 4 of them from 1 slime ball, once you get your new slime balls re-do process till you have all the slime balls in the world :).

this is also a great way to et many base emelents
