Here is a concise summary of the experiment:
**Experiment:** Dipping Fireworks in Liquid Nitrogen
**Objective:** To observe the effects of liquid nitrogen on fireworks' performance
**Tests Conducted:**
1. **Smoke Flares:**
* Normal conditions: Slow, steady burn with colorful smoke
* Liquid Nitrogen (LN2): Fuses initially extinguished; slow, condensed smoke when re-lit with a blowtorch
2. **Artillery Shells:**
* Normal conditions: Exploded at 80-100 ft height
* LN2: Reduced explosion height (40-50 ft) with less punch
3. **10-Shot Aerial:**
* LN2: First aerial shot only 20 ft high, landed without exploding (due to excessive cold)
**Key Observations:**
* Liquid nitrogen significantly slows down fireworks' reactions
* Fuses often extinguished or struggled to ignite in LN2 conditions
* Explosions were less powerful and lower in height when frozen
* Colored particles from smoke powder temporarily colored the liquid nitrogen (but not the nitrogen itself)
Here are the key facts extracted from the text, without opinions, in short sentences with numbers:
**Experiment Setup**
1. The experiment involves dipping fireworks in liquid nitrogen to observe their reaction.
2. Three types of fireworks were used: Mammoth smoke grenades, artillery shells, and a 10-shot aerial.
**Smoke Grenades**
3. Under normal conditions, the smoke grenades burned steadily for the same period and produced colorful smoke.
4. When frozen in liquid nitrogen, the smoke grenades' fuses initially went out upon ignition.
5. Applying a blowtorch could reignite the frozen smoke grenades, producing thicker, more condensed smoke.
6. The smoke grenades' reactions slowed down after being submerged in liquid nitrogen.
**Liquid Nitrogen Observations**
7. Submerging smoke powder in liquid nitrogen colored the liquid nitrogen yellow/orange temporarily.
8. The coloring was due to suspended particles, not a change in the liquid nitrogen itself.
9. Pouring out the colored liquid nitrogen revealed no lasting color change in the liquid.
**Artillery Shells**
10. Normally, an artillery shell exploded around 80-100 feet in the air.
11. When frozen in liquid nitrogen, the artillery shell exploded at a significantly lower height (around 40-50 feet).
**10-Shot Aerial**
12. The 10-shot aerial's fuse stopped short of the container after being submerged in liquid nitrogen.
13. Manually lighting the fuse resulted in only one aerial shooting off, reaching about 20 feet in the air before landing and spinning out.
14. The gunpowder from the aerial appeared to have fallen out, and the stars inside remained unignited, possibly due to the cold temperature.
**Miscellaneous**
15. The experiment was inspired by a comment from Thomas Dopkowski.
16. A future video may involve safely disposing of the unignited fireworks in a "Crackle Ball" experiment.
