Remember, no pic and it never happened.

That bowl was perfect right up until that last cut...

I'm not sure how thin your first bowl is but it looks thin enough to dry on it's own without the need for DNA. I do this a lot and a bowl 3/8" to 1/2" thick will dry in just a few weeks or less without me doing anything but putting it up somewhere without a lot of air movement or direct sun.

The only tip I know of would be that after you let it dry for a few minutes you wrap the outside in newspaper but leave the inside open so it drys faster from the inside out causing the wood to contract evenly on itself. After it drys that way for a week or two, or until it stops losing weight, then you can do the final turning and it should be stable. Other than that I've never tried it myself but have been really interested in attempting it to see how it works.

I want to die quietly in my sleep like my grandfather, not screaming in terror like the passengers of his car.

john, this bowl is about 3/16 wall thickness. im sure it would have dryed on its own over a short period of time but i was interested in the whole dna process. i know every wood is different and reacts diferently, but how much warping are you experiencing? on this one it wasnt an issue since it was small. but i just inspected the larger one i soaked and it has a fair amount of warp to it...i left my ten percent wall thickness so im all set, but just curious.
