Step 1: WATCH VIDEO!!!
To see this ghost projection in action and to see step by step video tutorial, watch video I made for this instructable.
First you need these things shown in the picture. Projector (got mine here), window ;) and transparent curtains. and a PC or a laptop.
also if you don't have a projector, GEARBEST.COM is offering lots of quality projectors for very affordable price. they also sell lots of amazing tech and just awesome stuff in general. so go check them out. :)
attach curtains to the curtain rail. I used some clamps to cover window with curtain but you could just use curtain rings. the reason I used clamps is so I can stretch curtain so it's straight.
Find a ghost video fx on youtube. like the ones I used.
ghost projections fx
or you can buy atmosfear fx dvd with lots of cool effects which costs like 30 dollars. then point projector onto a window and play the video. you should be able to see amazing ghost hologram. and it looks even cooler from outside. I actually got few kids scared while I was testing it. and it's not even halloween yet. :D
