after 5 minutes in the oven, you flip the record [which will be flopping down over the first bowl] into a larger bowl and start manipulating it into your desired shape. if you're not happy with it, simply put it back in the oven for a little while longer. its that easy!
don't even flip it over! just take the bigger bowl upside-down and smush it on top of the record that is flopping over the smaller bowl!
you know those mixing bowls you have? metal or glass, they all nest in eachother because they decrease in size... go get two of the bowls that fit eachother and use them
