Why yes !
When Hydrology9 is in operations, (such as when it is in heating, ready to inhale or in standby) press and hold the Hydrology9 operational button for 3 seconds enters the "PARTY MODE". PARTY MODE starts random colored quick flashing LED light rotation while maintains the previously selected temperature for 10 minutes. Great for passing the Hydrology9 around with a group of friends or random strangers.
LAVA LAMP MODE
When Hydrology9 is on but not in operations (such as when you press 3 times to turn Hydrology9 on, and it flashed green 3 times but has not selected a temperature for heating), press and hold the Hydrology9 operational button for 3 seconds enters the "LAVA LAMP MODE". LAVA LAMP MODE starts a slow LED light rotation, but does not generate any heat. Great for sitting the Hydrology 9 on a table and just staring at it after a session.
