I found this Lava Lamp recipe, but i dought if it is the one you are looking
for.
Lava Lamp
1/4 oz. Galliano
1/4 oz. Bacardi White Rum
1/4 oz. Banana Liqueur
Dash of Blue Curacao
Directions:
1) Pour in order in a double shot glass.
2) Lightly pour the dash of blue Curaçao in last, so it falls through the
other ingredients giving it the look of a lava lamp.
