For our thriller research we decided to try out some of ideas to see if they would work. To achieve a smoke effect we used powder paint and blew it with a hairdryer. We did this in blue and green as it gave a poison look. we also tried hanging a fork up with clear string. this worked well. However, it did not look good with the camera flash as you could see the shine of the string. For this reason, when we use this technique we will know to use low key lighting to use shadows. it will also give a darker feel to he effect.
