A YouTube video features an experiment where the host tests the effects of liquid nitrogen on various fireworks, including smoke flares, artillery shells, and aerials. The host first tests each type of firework under normal conditions, then submerges them in liquid nitrogen and observes the changes in their behavior.
The results show that the liquid nitrogen significantly slows down the reactions of the fireworks, causing them to burn more slowly and produce less energetic explosions. The host also notes that the liquid nitrogen colors the smoke powder yellow.
The most dramatic experiment is with a 10-shot aerial, which the host submerges in liquid nitrogen and then lights off. However, the fuse is too short and doesn't reach the fireworks, so the host has to relight it. The aerials eventually shoot off, but they only reach about 20 feet in the air before landing on the ground.
The host concludes that the liquid nitrogen makes the fireworks go off less dramatically, but it's still a fun and interesting experiment. The video ends with the host suggesting that they might combine the unexploded fireworks into a giant crackle ball experiment for a future video.
Here are the key facts extracted from the text:
1. The experiment involves submerging fireworks in liquid nitrogen to see how they react.
2. The experiment was suggested by a viewer named Thomas Kowski.
3. The experiment is being conducted to celebrate independence day.
4. The equipment used includes a styrofoam cooler, liquid nitrogen, tongs, and fireworks.
5. The first set of fireworks tested were smoke grenades.
6. The smoke grenades were lit before and after being submerged in liquid nitrogen to compare their behavior.
7. When the smoke grenades were submerged in liquid nitrogen, they did not ignite immediately.
8. One of the smoke grenades exploded when lit with a blowtorch while submerged in liquid nitrogen.
9. The experiment was repeated with artillery shells.
10. The artillery shells were also submerged in liquid nitrogen and then lit.
11. When the artillery shells were lit, they shot up to a lower height than usual and did not explode as forcefully.
12. The experiment was repeated with a 10-shot aerial firework.
13. The aerial firework was submerged in liquid nitrogen and then lit.
14. The fuse of the aerial firework burned out before reaching the container.
15. When the aerial firework was relit, it only shot up to a height of about 20 feet and then fell to the ground.
16. The gunpowder in the aerial firework did not ignite properly due to the cold temperature.
17. The experiment was stopped to avoid any potential danger.
18. The remaining fireworks will be used in a future experiment to create a giant crackle ball.
