How to make "smoke" with dry ice

Place 2 - 4 kg dry ice into a bucket of warm water, or urn for every 15 minutes required. This will generate a lot of "smoke", depending upon the temperature of the water and the size of the dry ice pieces. Warmer water will generate more "smoke", which is much more visible. In addition, very hot water will add rising steam to the vapour cloud which will eventually flow towards the ground.
 

Caution: the water vapour will also dampen the area as it flows across - floors may become slippery.
 

Place dry ice in the jacuzzi to create a romantic atmosphere, also in a swimming pool for special events, e.g. weddings.
