Dr Beaker

Each player has a beaker with six compartments around the edge for molecules, which are represented by plastic balls in three colors; two spaces for molecules are in the center of the beaker, with the beaker having a rotating platform in it. Each player also has a stirring rod, and when someone turns over a challenge card, everyone must race to arrange the molecules in their beaker to match the pattern showing on the card — but they must use only their rod to do so, moving the molecules around the beaker through the openings in the compartments. As soon as a player matches the pattern, they claim the card, then flip over a new one, with everyone continuing to play with whatever arrangement of molecules they currently have.
