Learn physics with killing time app!You are Maxwell's demon, who is aiming to decrease the entropy in the room.You are allowed to open and close the gate to selectively pass the particles through it.Drag the screen vertically to move the gate up/down, tap the left bottom button to open/close it.Your goal is to move all red particles to one side of the room and all blue ones to another side.Fight with increasing entropy!Latest version 1.1.21.1.2Ads removed.1.1.1Velocity distribution select menu added to the settings.1.1.0Velocity distribution changed. Red (hot) particles move faster, Blue (cold) ones slower.
