Wow, just found this thread and the blaster looks amazing, great work. I have a production made stunt tri-barrel that I have been meaning to try to bring up to scratch for ages so this will inspire me to get on with it. On the point with the clear container for the fluid and alien I had the same dilemma and opted for using the contents of one of those oil and water toy balls so that if you left it standing the fluid would be clear on top and blue on the bottom but if moved the fluid would mix and be all blue until it settled again, but my container is much smaller and a round flying saucer shape. Had this up and running once and it looked good but did have a slight leakage problem so back to the drawing board. Anyway will watch your thread with great interest and keep up the great work! :thumbsup
