We watch as one craftsman blows a bubble into a ribbed mold, has one end of the bubble cut off by an assistant, and then twirls his blowpipe about its axis to get the bubble to open, like a flower bud opening.
Parasjagu puhub üks meister klaasimulli ribidega vormi, laseb abilisel ühe mulli otsa ära lõigata ning keerab klaasipiipu ümber selle telje, et mull avaneks nagu lilleõis.
