Turning powdered heroin into solid?

[black kat]

Is there any simple way to do this without needing a degree in chemistry?

I got my hands into a small amount of powder(i usually get it in rocks but powder was the only thing available at the time) and i find it way easier to store and generally manage it when its in some kind of rock or solid form.
Even solidifing it in some kind of crappy cube-like form or something would do.

Anything like this possible?
