In the course of the 18th century, the circulation of skills and technical exchange led to further developments.
在十八世纪，技艺和技术交流引发了进一步发展。
Fireworks specialists from Italy began to travel around Europe staging displays for many of the European courts.

The architect and stage designer Giovanni Servandoni composed grand displays in Paris, featuring colorfully painted temples and triumphal arches.
建筑师和舞台设计师吉奥万尼·赛凡多尼在巴黎设计了非常宏伟壮观的表演，展示了彩色的寺庙和凯旋门。

As in the previous century, fireworks provided resources for demonstrating scientific laws and theories, as well as new discoveries, and displays now showed a fascinated public the curious phenomenon of electricity.
在上个世纪，烟花为展示科学规律理论以及新发现提供了资源，而现在，烟花表演也向深深着迷的民众们展示了有趣的电现象。
