212: Drone fireworks


Traditional fireworks create a toxic fog of fine particulates, poisonous aerosols and heavy metals.


Drones were used in several cities to ring in 2021. In London a 10-minute show used more than 300 drones which were flown around the Millenium Dome after the annual fireworks display at the London Eye was cancelled.

The London Show  ended with the image of a sea turtle and ended with Sir David Attenborough calling for people to work in 2021 to help our ‘fragile’ planet. In Scotland 150 drones were part of a three-part choreographed show called “Fare Well” to say bye to 2020 and welcome

Three months’ before, during the night of September 20, some 3,051 drones took to the skies above Zhuhai, Guangdong, China to break the record for the most Unmanned Aerial Vehicles (UAVs) airborne simultaneously.

During this official challenge, the design executive team represented achievements of Chinese space science and technology in the night sky, such as the Tiangong-1, Beidou satellite system and China’s space station.

The benchmark for this record was set by a 2,200 drone display in Russia on September 4, 2020. This broke the Guinness World Records title set by Intel Corporation (USA) with 2,066 drones in Folsom, California, USA on 15 July 2018.

Another solution is the Japanese solution of sticky rice fireworks, which offers fireworks with far less smoke. The rice cares are prepared, toasted then broken apart before heating them again and making paste once more. Although this takes a bit of effort, it produces the ultimate paste.

If the adhesive strength is neither too weak nor too strong, a beautiful hoshi combustion will not be achieved

Thailand rang in the New Year 2021 with a 1.4 km display of 20,000 sticky rice fireworks along Bangkok’s Chao Phraya riverfront as eco-friendly message of hope to the world.
