Are the fireworks in the Winter Olympics real or electronic?

The fireworks in the Winter Olympics are real. At first, the structure of fireworks was relatively simple, with only two layers inside. The first layer is the outer cylinder, and the inner cylinder can generally contain gunpowder, while the ball in the inner cylinder is generally composed of detonator, gunpowder and light ball. Much like several layers of propulsion devices when a rocket is launched. After the gunpowder in the outer cylinder sent the whole fireworks into the air, it exploded inside, and then the light beads inside spread to form some simple fireworks patterns.

Fireworks design for Winter Olympics

The "big footprints" of fireworks in the sky at the opening ceremony of Beijing 2008 Olympic Games are still impressive. As the chief designer of visual arts for the opening ceremony of the Winter Olympics, Cai Guoqiang once again partnered with Zhang Yimou to add luster to the opening ceremony with unique fireworks. In an exclusive interview with reporters, he said that under the creative principle of "simplicity, safety and brilliance", the total amount of fireworks set off this time was less than 10% of that of the 2008 Olympic Games.
