Homemade Fog Machine for Show Choir Risers
You can create the mystical effect of rolling fog pouring from a show choir riser by making a homemade fog machine. A homemade dry-ice machine can be assembled in a few minutes using common household items. The machines produce fog for at least 10 minutes without reloading. Give a singing group an extra edge by positioning a homemade machine behind a riser.
