Gone are the 'light blue touch paper and retire a safe distance' days. Shells are now launched using compressed air. No burning black powder means no smoke drifting over the residential neighborhoods, plus a safer show. Best of all the new system is more precise and can launch shells higher than black powder, enabling spectacular new effects. An additional article: The future of theme park fireworks covers some of the pros and cons of compressed air launch systems." We mentioned this earlier.
