Dry ice is an excellent tool to create outdoor smoke effects. By simply dropping 50 pounds of it into the water of a heated pool or jacuzzi, it produces smoke for 1-2 hours depending on the temperature and size of the chunks, which is ideal for events and parties. This method is not only affordable but also versatile and safe, making it an excellent option for creating theatrical or atmospheric effects without risking exposure to harmful chemicals or damaging equipment as well.
