I was given a this skull by a family member. It is so cool and unique I just had to do something with it!
In short I placed 3 RGB sections around the skull, added a 555 timer to make the leds flash and filled it with water to create awesome patterns on the walls that surround it. I also placed a small fan over the mouth of the bottle to make the water ripple.

Step 1: things needed
If you have seen my instructable on how to make a dog safety collar https://www.instructables.com/id/Flashing-LED-dog-saftey-collar/ you will notice that the 555 timer schematic is almost the same. now it can be the same but I chose to swap out one resistor for a potentiometer, you dont have to do this but it allows me to controll the flash rate.
47k resistor (two if not using the pot)
2.2 uf cap
crystal head vodka bottle
3 sections of a rgb led strip
small 12vdc fan (optional)
9volt power supply
