Mint Bubbleworks

Fill the three mint jars with exactly 8, 16 and 8 before the ten-bubble batch runs out. Tap either bottom feeder to release the next bubble. Straight air sends it to the outer jar; inward air bends either feeder into the center jar. Bubbles rise and fuse with an equal bubble at the mouth, cascading through equal layers. A jar seals only when its one remaining bubble exactly matches its label. Sealed jars reject new launches. More than three layers or a bubble larger than its jar bursts the batch. Changing the fan costs no bubbles. The queue is fixed and visible: split it between jars rather than feeding everything into one tube. Keyboard: Tab and Enter/Space operate buttons; R restarts.
