Trick? No trick! I thought the rosin was exploding!
But seriously, I just took the rosin (still wrapped in paper) out of the case and microwaved it for 6 seconds, twice. The reason I did it twice (rather than 12 seconds all at once) was that I wanted to see how it reacted. I wanted it more sticky, sure, but not all gooey and messy. It worked out fine.
Unless you can find other posts/answers to the contrary, I suggest that you "nuke" it in short bursts of about 5-6 seconds until you are satisfied with the consistency. The way I would describe mine would be "somewhat malleable", and it rubbed off very nicely onto the bow hair. Good luck!
Never try this on your bass though, even if you are after a more mellow tone ... I'm sure the machine heads would cause some nice sparks!
