Create a romantic dancing-on-clouds effect for your first dance. Dry ice produces the perfect low-lying fog that flows across the ground. A dedicated dry ice smoke machine should be used with the dry ice. You can hire these from special effects companies like Team FX or Film Equipment Hire Ireland. The recommended type of dry ice is dependent on the type of dry ice smoke machine that you hire. Typically dry ice pellets or a 10kg block of dry ice is best. The hire company will be able to advise you which is most suitable.
