Dancing Paint on a speaker ~ Neon Lights
Love making a mess !!! This was right up my street ..... take one second hand speaker purchased from a charity shop, remove outer cover of speaker and stretch a balloon over the internal speaker. Place several blobs of paint on balloon... next synchronize taking high speed images using two speedlites at the same time playing base music very loudly. You will only get about 3 to 5 shots at each one because the paint blends together really quickly.
Did I mention messy ... cover the room with plastic, paint will get everywhere.
Cross Polarisation
Created by using a polarised filter on the camera with a white image on a LCD computer screen as a light source behind the subject.
Turning the polariser will reveal the stress in the pastic in a beautiful multicoloured pattern.
