This canister of gumballs contains little marble blueberry gums, and there are occasional white color gums that are yogurt flavored.  You can't tell by the color of the hard candy shell, but some of the blueberry gums are actually a little bit sour.  You can blow bubbles with this but you gotta eat like 1/3 of the container to get a decent sized one going.  This is a fun one and I really enjoy the packaging a lot, makes for a great gift.
