Step 5Making smoke
Smoke may be a bit misleading but this was actually the most spectacular part of the show. Watch the video at the start to see.
It was made from a teaspoon of coco powder in 2 "shooters" powered by balloons. Each balloon sat in a holder hidden inside the box. A pin held the balloon in place. A slow turning motor pulled a string attached to the pin. (the motor turned too slow so I added the arms to increase the radius) Once pulled, the air rushes through tubing to the pan. Inside the tower of the pan is a loop in the tube. This holds the coco powder close to the end and allows me to separate the tubes between the pan and the box without the coco spilling out the bottom.
When this went off we somehow got 4 bursts out of 2 shooters. I still don't know how it happened but I guess it is better to get more than you expected than less.
